Features:

  • Click more. Scroll more. Do more. Logitech Marathon Mouse M705 uses far less power than comparable wireless mice from other companies. That means you can go up to three full years between battery changes.
  • Hyper-fast scrolling lets you fly through long documents and Web pages with a single spin of a nearly frictionless metal scroll wheel.
  • The sculpted, right-hand shape guides your hand to a naturally comfortable position and places customizable control within your reach. Two thumb buttons lets you move quickly between Web pages.
  • The tiny Logitech Unifying receiver stays in your laptop. There's no need to unplug it when you move around, so there's less worry of it being broken or lost. And you can easily add compatible wireless mice and keyboards to the same wireless receiver.
  • Laser grade tracking delivers smooth, responsive, precise cursor control on surfaces that cause problems for standard optical mice, such as polished or wood-grain tables.
New model not as bad as everyone is saying it is.

I used to have the old model of the M705 years ago. I used it primarily as a couch mouse and an occasional laptop mouse. I must be different from most people as I never used the extra button under the thumb, and I felt that it made the mouse feel just a little flimsier around that area due to how it would flex. Since I never used that button and it is all sturdy and doesn't move now I actually like the change. Something that doesn't come across very easily in the pictures is that the finish on the plastic is different. I hear a lot of people saying that it feels cheaper. I would disagree, it went from a slightly glossy finish to more of a matte finish, which I prefer. The sensor does look different on the bottom, but it works on almost every surface I have tried it on (Haven't tried glass, so I'm not going to vouch for that). The old sensor LOOKED nicer on the bottom, but this seems to preform very similarly. I purchased this mouse with about 4 other Logitech mice and this one came with Duracell batteries instead of cheap knock off batteries, which is nice. The rubber sections on the sides do feel different from how I remember them. I remember the rubber being very grippy, but softer. The rubber on the new mouse feels harder and more like it has a matte finish, which I do not mind. I would say the one very minor change that I didn't like as much as the old one is the scroll wheel. I remember liking the old scroll wheel a lot. The old one would click into place and as you would scroll it would snap between the notches very securely. I remember abusing it by scrolling the wheel freely and hitting the bottom to lock it down and being amazed that it never broke from that. The new scroll wheel doesn't notch into place with as much authority and feels like it may slip between notches easier. It offers less resistance than the old one, but due to that it feels less sturdy. Overall I think people are vastly over blowing how bad the new design is. I actually have a lot of issues with Logitech products, but this isn't one of them. This older model still is more ergonomic than the M720, and I would bet that since there is less rubber on this mouse it will age nicer than the M720, that rubber will get gross after you keep it in a dirty back pack and just through age. If you didn't use that old button its probably a fine mid range mouse that is getting more flack than it deserves.

Will never not love this mouse

This is probably the 5th mouse of this model I've bought over the years, and while they've modified it slightly a few times, the ergonomics and overall functionality of this model makes it the perfect mouse for me. I haven't bought so many because the old ones break down, but I put 12-14 hours per day of use into them, and the little teflon/plastic skids on the bottom wear down over time. I'm happy to purchase new ones, and now I have a few at home and one at work, and keep the old ones as a just-in-case. Ergonomically, I don't have huge hands, and with some bigger mice it seems like I have to shift my whole arm. This is small enough to where I can flick my wrist alone and quickly navigate everything. Yet, it's not "laptop mouse" small, and has plenty of features. I love the button that allows you to shift the mouse wheel between "clicky" or freewheeling - there are different times I may need one over the other. The amount of buttons is perfect. Left/right/middle press, wheel shifts left and right, a forward/back thumb button. Older models have the thumb downward press button you can define, but I never did use it for much so I'm not disappointed to lose it. Batteries in these things last forever, the laser tracks very well on anything that's not shiny, and the bottom skids allow smooth movement. Never had any issues with the unifying receiver, it's thin enough to just keep in a laptop even when in a bag, and it works well with my logitech keyboards too. The latest model is a bit different in terms of plastic - it feels much lighter overall, and the plastic seems thinner. I'm not sure if this will be a positive change or not, but it feels plenty sturdy to me. Not sure what else to cover here. For all my needs it works perfectly. I don't think it qualifies as a high-precision gaming mouse (you shouldn't be looking in wireless mice for that anyway), but for literally everything else it's great. Here's hoping they keep this model around for years to come.

Extreme battery life with back and forward buttons and a great feel

I love this mouse- I have one at work, and now one at home. It has a good ergonomic grip for the hand, with a smooth glide over my desk surface. I am an avid user of the back and forward buttons on a mouse, so I can't really bear using a regular two button with scroll wheel mouse This scroll wheel can either scroll smoothly or give the little bumps (which I prefer- most are like that) with just a press of the scroll button next to it. I don't really use the 5th button at the thumb grip, but its set to display a dashboard of all open windows for me to choose from- thus if I do accidentally hit it, I might find some benefit out of it. The clicking of the mouse isn't silent, but I like the feel of it (smooth and sensitive, but not to the point of accidental). I'm a very tactile/sensory-sensitive person, so these are all important things to me. I also love the extremely long battery life- I hate batteries, and if there was a way to have a solar mouse to match my solar keyboard, I would. This mouse uses a unifying receiver so I have it on the same receiver as my logitech solar keyboard (another excellent purchase, IMO). I've had my work mouse for two years, and have not yet had to change the batteries- and it gets a lot more usage than my home mouse ever will. I expect to get several more years out of the work mouse before I even think to check :-)

Good mouse after you figure it out

I bought this to replace my old Logitech mouse because I wanted one to fit my hand better. This does that but it will take some getting used to. I have large hands and my old mouse would cause cramps since it was a little small. Now I have a larger mouse that fits better. Now I have to get comfortable with the buttons being in different places but time will solve that. My only negative thing to say about it is the hyper speed wheel is way to sensitive. I adjusted the speed to 3 but it still jumps all over the place when using it, you better have a steady finger or what your looking at will jump up and down even when you think your finger is off it. It seems like the wheel will keep spinning if you move it to fast. All it takes is a light touch and your page is going by itself. My old mouse had notches that kept this from happening, I'm thinking about putting a little silicone glue in the wheel to control it or something like that. I might have to try a different brand. revised----This mouse has many adjustments and you can dial it in to your likes. A button on top changes the way the wheel works and now I have adjusted it to my perfect likes. Now after dialing it in I'm very happy with it and it now feels natural. revised-- I have found adjustments like the DPI button that has fixed my issues and now am happy with it. I jumped the gun on this one.

Decent Size for Large Hands

The Logitech M705 Marathon Wireless Mouse is the perfect companion for a laptop user with largish hands, without taking up a lot of space. The pic includes a male hand by the handle Handy that needs size L in most gloves: 7.5” from palm to the tip of the longest finger, and a little wider for the spread between thumb tip and pinky tip. It comes with a Logitech unifying receiver operating at 2.4 GHz wireless, also pictured, which has proven far more reliable than Handy’s old blue-tooth mouse (blue-tooth is the problem, not the mouse). The M705 is easy to set up and quite responsive with its “Laser grade tracking” of the 1000 sensor resolution variety. That is, it works on most surfaces without being a pain in the posterior. The receiver is small enough to leave in the laptop at all times, and currently resides in a USB 2.0 port. It operates just fine up to several feet away (up to 10m according to Logitech), just for those hands out there with really, really long arms. Or, it works as a sensible presentation clicker, though an inexpensive wireless presenter is highly recommended (such as the DinoFire Wireless Presenter). Should Handy wish to add a wireless keyboard (Logitech of course), this little receiver will handle that too. As for battery life, Handy is currently testing it and will perhaps get back to you in threeish years when the juice finally runs out. Seriously. Handy has a smaller blue-tooth Logitech mouse that runs on a single double AA that lasts for over a year of daily use before it red-lines, so Handy remains optimistic regarding the claim of the new guy on the block, which even came with the required two Duracell AA batteries for juicing the mouse (heh, heh, heh). Handy hopes the M705 lasts longer than its batteries. The mouse has seven buttons, including a tiltable wheel with fast-scroll. The last is easily switched to a standard incremental scroll, which is Handy’s preference, and most of the buttons are programmable via Logitech’s software. For the full specs and software downloads for this mouse visit Logitech’s website via your particular brand of magnificent Google-foo. Handy would include a link here, but would like to stay friends with Amazon ♥. The additional Logitech software is not necessary unless one desires to program the buttons with other than default settings (forward and backward browsing, middle click, etc.), at least on Windows 7 and Windows 10 in Handy’s limited experience. So far Handy has used the M705 for 8-10 hours a day for about two weeks doing web-browsing, navigating Windows land, graphic design via Affinity Photo and Design, along with numerous other productivity tasks, and gaming, of course, without getting cramped. What hand does not like a little Clash Royale, Terreria, League of Legends, Rocket League, and ad nauseam, not to mention Candy Crush? Please note, however, that the M705 is not technically a gaming mouse, as the lack of an additional 200 buttons indicates. Handy purchased the M705 fair-and-square, and did not participate in the dubious activity of a paid promotion.

This has been one of our favorites for awhile now

Both the keyboard and the mouse within this series has been one of our favorites for quite awhile now. Enough to say that when you walk around the office and look for any mouse that has been heavily warn (rubber grips for example), yet still works just fine (and we have refused to replace it) , chances are, it will say M705 on the bottom. It supports their USB unifying receiver perfectly and it feels absolutely great in the hand (with very few mentions throughout the years about discomfort after long hours of use). For games, we wouldn't say that it is perfect. You do have to find the best mousepad for it as some can cause it not to move around as smoothly when you give is a slow test in a straight line. This doesn't mean you couldn't use it for such though. We do it all the time in testing of games or the playing off on off/break times. In the end though, the most important part is it feels great in the hand. It lasts forever, and the batteries do to. Button locations feel natural and it is nice to be able to switch between the two modes of the wheel (smooth or step). **If you have found our review helpful, please vote it as helpful below so I know. This helps me provide quality feedback in the future.

Great Feel & Customization with Options App

I bought this to replace an older Logitech M275 mouse that still used the old (non-Unifying) dongle and one of the biggest concerns I had was going to be the fit in my hand. After reading a whole series of mixed reviews on several different Logitech mice I went ahead and just decided to give this one a shot. It is actually slightly larger than my M275 which I am not upset with at all as the M705 adds a little more ergonomic slope so that the hand fits more naturally in a resting position on top of the mouse. I would say I have normal sized dude hands, but since no one seems to have mentioned this before, and yes it is weird to mention, but my hand is 8" from bottom of palm pad to top of middle finger. This allows my hand to rest naturally on the mouse with the base of my palm resting on the desk, and firm purchase on the mouse, with solid articulation left and right using my wrist, and forwards and backwards using my finger extension. My mouse came with 2x Duracell "AA" batteries so that was nice to not have to use my own batteries. I have heard people mention that the mouse will happily run off of a single battery, especially if you want the mouse to be a bit lighter. This thing slides so easily across my wood desk that I'm not sure lighter would be the best idea, but if I end up traveling with it, that little extra bit might actually come in handy. Plugging the mouse in right out of the box enabled all of the basic features immediately. In order to setup the individual buttons on the mouse you have to install the Logitech Options software which I had to go find on their website myself. Once installed it saw my receiver, my mouse, and presented me with the various options to customize the buttons. There are actually a huge list of actions you can attach to each button which was exciting. In fact there are about 66 different things you can pick from, and that doesn't include the complex actions like opening files, browsing to specific URLs, launching an application, etc. The last feature that I knew nothing about until I was sitting here playing with it is the little black button on the spine of the mouse just behind the scroll wheel. When you click this down it actually removes all tension from the scroll wheel and it will spin effortlessly and if you give it a spirited scroll will continue to keep rolling like a true wheel. This has been amazing in scrolling super quickly down long web pages, though if not careful it will start scrolling again with very little effort. Clicking the button again puts the tension back on the wheel where it has soft friction points like a traditional mouse where the scroll action is much more firm, but admittedly not nearly as smooth and luxurious feeling as when the tension is off. In short, I'm loving this new mouse and think it is definitely a great upgrade from my older mouse. I can see where it might not work or feel great for everyone, especially if you're coming from a really old Logitech (think before logo change) where the frame was much larger. Overall though, I'm super pleased and for the price especially I think it was well worth it.

Love the Free-Wheeling Speed of Scrolling

Laser technology This mouse uses a laser to detect movement with accuracy across a variety of surface types, including glass. Because of the above statement in the Best Buy description I bought two of these (one for myself and one for my wife), they work great on any and every surface we had tried. Scroll wheel Supports click-to-click scrolling, so you can quickly navigate lists, slides, images and more. This is another great feature of this mouse. Best mouse I have owned in more than 25 years. The Logitech M705 model appears to be very responsive and relatively comfortable to the hand. This makes it ideal if you need to utilize a mouse for long periods of time. The only major complaint I have with this mouse is, due to its design, the back button can be inadvertently clicked by your thumb while browsing. Pros: Very responsive, long advertised battery life (3 yrs) Cons: Louder than desired mouse clicks, location of back button

Works as expected.

I started having issues with the mouse that came as a keyboard / mouse combo set after it fell off the desk onto the tile floor. I found this exact model was sold separately and decided to finally replace the wounded one. I used the old one for well over a year and never once had to replace the batteries. And I use my computer daily for a minimum of 3-5 hours depending on how much work I bring home with me. There is a USB dongle included, but I find it is easier to use the "Logitech Unifying Software" to pair the mouse with the same dongle as the keyboard, if you have an existing Logitech mouse or keyboard. The software is free from Logitech on their website. This keeps you from having to use 2 different dongles and helps keep you USB ports on your computer open. The scroll wheel has two options which is nice if you are reading long single page documents. You can select / deselect the scroll button and the scroll wheel will freely scroll. Press it again and it will scroll in set intervals. Some people may not find this feature useful, but to each their own. I have been a long time user of Logitech products both for personal and professional use, and this one has not disappointed.

The little mouse that could.

This mouse model has been around for a LONG time. We have three of them that are from sometime before 2010. While technically a mobile mouse, we find them perfect for desktop systems. They have outlived what they were originally connected to, having gone through at least three generations of computers during that time -- from huge white box PC towers to sleek aluminum iMacs today. One has been used pretty hard for years on end, and is finally just starting to have some occasional left button issues, so we are replacing it proactively. The other two still work great. One works in a sometimes unheated environment, and has functioned fine in temperatures as low as 10 degrees. The 'velvetized' plastic used on the sides has not gone tacky like on many remotes. While they do not have the sampling precision of a gaming or graphics input device, they are great for general purpose computing. They are relatively light and easy to handle, not too big or bulky, and are not too complicated to use. The weighted free-wheeling wheel has a good feel to it at this price point -- not clunky at all -- but is occasionally sensitive to unwanted scrolling movement when the mouse is moving. And they last absolutely forever on a top-end set of batteries. We put lithiums in ours when purchased many years ago -- and they still measure at 100% seven or eight years later. Truly a lifetime battery. The batteries from the worn out mouse are going right into the new one. Hopefully, the new production is as sturdy and trouble-free as the old ones. Other than the logo change, they look and feel pretty much identical to the pre-2010 ones. We use ours on a mousepad, so haven't had any issues with plastic glides wearing prematurely over the years. The receivers are fairly stable, other than the unifying software being buggy in OS X. The software is the weakest point of this model. We've had some pretty expensive input devices over the years. But for around $20, if this one lasts for three or four years in heavy use, it's worth it. For the seven or eight years (and counting) that we've gotten out of ours, they are a steal.
