best mouse i've ever bought for $20

great mouse. hope the battery life lasts as long as it says b/c my much more expensive logitech mouse burns through batteries like crazy. love that i can get the super fast scroll wheel or incremented scroll on a low price mouse. mouse feels very comfortable in my hand. update re: tracking on the macbook: i still have to set the tracking speed to max, but on a very smooth surface the performance is much better. changing review to 5 stars. I don't think you can beat the performance of this mouse for this price. will do update, as I may be also using this on my windows 7 pc, but on a macbook pro osx 10 with tracking at max, mouse still tracks pretty slow. i like my tracking fast. it might be the mouse - so that's why not 5 stars.

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.

Minor hassle for MacOS but well worth the effort. Requires 2 downloads. Read This first.

First to establish the Logitech Control Panel in your System preferences: https://support.logitech.com/en_us/software/logitech-control-center-for-macintosh-os-x Then download Logitech Options for your particular mouse, in this case the Marathon M705: https://support.logitech.com/en_us/software/logitech-control-center-for-macintosh-os-x The second download is ESSENTIAL. Logitech's unifying software within the Logitech Panel in your System Preferences does not work. You MUST identify your mouse at the Logitech website and download the corresponding software which will establish a second icon called Logitech Options from which you can configure your mouse. It has a computer mouse icon and sits next to the LOGI Control Panel icon. Click on and open the Options icon and you will see a slick looking configuration panel. Yeah, the overall effort is kind of unbelievable and requires a couple of restarts, but at least with a company like Logitech, you are assured that they're on top of these software issues and bug fixes. I certainly would NOT want to be stranded in a no mans land of zero technical support from a no-name company. This Logitech mouse is worth the performance upgrade. The device is solid, well made and works like a dream. Good riddance to the tangled wires of a standard mouse. No clue about battery life since I just installed this. Gaming? Perfect only for standard PC/Mac games and screen savers, obviously not "hardcore" gaming.

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.

A couple of features you might overlook if you don't read the whole manual

This is a great mouse for reasons all stated in other reviews. However, some complaints I've seen about this mouse in other websites come from people who have not read the manual and missed some features this mouse offers that address their complaints. You don't know what to do with the receiver when transporting your laptop? First, the mouse does have a compartment for the receiver. The receiver is tiny already, so most people will just leave it inserted in their laptops during transport. However if you wish to store it with the mouse, you can do so. It does not require you to take out the batteries themselves to store the receiver, but you do have to take the battery cover off to access the compartment. The mouse is too heavy for you? The most awesome and rarely mentioned feature about the mouse is the ability to modify its weight and center of gravity by only using one AA battery instead of two. The reason this is so cool is because it gives you an option to lower the weight of the mouse if you think it is too heavy with 2 batteries (I thought so). You can also to change the way the weight feels in your hand by placing the battery in the slot closest to the center of the mouse or closer to the back of the mouse. Some people prefer the weight of the mouse to be on the back while others prefer it to be more centered. I left mine in the center. How does it work with just one battery? If you notice, the two batteries in its compartment are used in parallel (both installed looking the same way), instead of 'in series' like most electronics do (going the opposite way). The mouse works on 1.5 volts instead of 3.0 volts like the usual 2 AA battery equipment would. This is what permits the 3 year battery time. Of course, using one battery means it will probably only last about half the time as using two. I'm not an electrical engineer so I don't have much knowledge regarding the efficiency of using two instead of one battery. How does this compare to other logitech mice in size and weight? I use a wired Logitech G9 Laser Mouse for my desktop pc, which weights 122 grams with no additional optional weights inside. I just add 4 grams of weight for my preferences. In comparison the Marathon M705 weighs 88 grams without batteries. With one battery it weighs 112 grams and 136 grams with two. The batteries it comes with weigh 24 grams each (other brands of batteries might have a different weight). So, with two batteries this mouse is heavier than a G9 even though it is slightly shorter lengthwise and slightly thinner as well. The M705 is about 4.5 inches long, 2.8 inches wide, and 1.5 inches tall. As a G9 user, this was the closest feel I could find in a wireless mouse. All other ones either felt too big forcing you to place your entire palm on them and disallow an optional claw grip or felt not wide enough for my hands. I enjoy the width of the G9, and even though the M705 is not as wide and connecting with as much of my palm as I would want it, it does not make my hand cramp up as most other narrower portable mice and I can use it for games without feeling like I'm using a non-full-featured mouse. It is the perfect blend of portable and full sized featured mouse. My only gripes: The DPI on the mouse cannot be modified. This is understandable as it is not a gaming mouse. When compared to the G9, it seems that is it is permanently set at 1000 dpi. Another problem is that it has negative acceleration. This means that when you move it fast from side to side, it registers less movement the faster you move it. This only occurs at high speed movements, such as doing a quick turn on a first person shooter game. Again, I don't detract from the rating of the mouse, because it is not meant for gaming, but I thought I would include this in the review as some people might want this information. Edit: I'm adding an image of the M705 vs G9 to the product page so you can judge the size difference. I looked for this online but it seems not too many G9 owners have yet bought this mouse since it hasn't been out for very long.

Best wireless mouse for everyday use!

Best wireless mouse for daily use and everyday tasks. I am a heavy duty user, and have two M705 mice, one at home and one in my backpack. The battery does NOT last three years if you are hardcore. Expect about an year in that case. By the time you replace the battery a second time, you will notice little tracking glitches, and the occasional lag when you click on a link. So, for heavy use, expect the batteries to last about a year, and the mouse about two. After about a year you might want to replace the pads underneath the mouse, as well (Mouse Skatez / Mouse Feet for Logitech M705 (2 sets of replacement mice feet)), and if you carry yours in backpack or computer bag, consider a hard shell case for it (For Logitech Wireless Marathon Mouse M705 Travel EVA Hard Protective Case Carrying Pouch Cover Bag Compact sizes by Hermitshell). Over the years I have bought a handful of M705s, and I cannot say enough good things about them!

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 :-)

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.

It's a good mouse, Brent.

This mouse replaced my Logitech MouseMan after, I kid you not, 18 years of faithful service and no less than five different computers. I loved that mouse. I took it apart and cleaned it meticulously on the regular to to keep it in good working order because using it just felt good. The buttons had good action, it fit my hand, and dang it, we had been through so much together. It still works, but it's been retired to my laptop bag for only occasional use because it is starting to show its age. This mouse lives up to its predecessor. The only thing I miss is the action on the middle wheel-button is not as good as my MouseMan. But the conformation to my hand is even better, the weight and glide are great, and I really, really like having that extra thumb button. I've never met a wireless mouse I liked until now— having to tug on the ol' MouseMan's cord to slacken it around the clutter on my desk was starting to cramp my style. 13/10 hope to get nearly a two decades out of this one, too.

What a great value wireless mouse!

This Mouse is AMAZING! Picked it up for under 15 dollars and what an upgrade from the cheap 10 dollar mouse I was using before. A great upgrade from the basic mouse I was using before. Feels quality and has good weight and shape. it is a medium sized moue with 3 programmable thumb buttons, notched or free spinning muddle button with side clicks on the wheel as well. All of the buttons can be changed via Setpoint to other pre determined functions or a keystroke. Just what I was looking for to add some capability and quality to my laptop wireless mouse solution. PRO's: well weighted substantial feel 3 year battery life programmable buttons with Logitech Set Point software 3 yes 3 side buttons ( I didn't even realize until I was using it but there is another button in the thumb grip accurate and responsive wheel with unlock so you can free spin it or have it notched (helps to get to the end of long documents with one flick) CONS: not too flashy I guess wheel not as solid feeling as my G700's Not recommended for online gaming where response is primary concern
