What a fantastic product! I started looking into the world of vertical mice after experiencing some wrist discomfort from the use of a traditional mouse. Of course, the first search hit was Evoluent Vertical Mouse. They were the first to market with a product like this, plus they have the whole University of California academic cachet behind them. For YEARS Evoluent was the ONLY player on the vertical mouse market without competition. As a result, the technology and finish of their product is still stuck in the past. Think those ugly white Microsoft optical mice we all used in the late 90s when optical mice were a novelty. The Evoluent mice have the exact same feel, and even worse tracking capability! In Evoluent's defense, their product does relieve wrist strain, but so does Anker vertical mouse...... for only $20! So let's compare the two products side by side, Evoluent vs Anker. Note that I am just over 7 inches from my wrist crease to the tip of my middle finger. This puts me right on the border for Evoluent between normal and small versions. If you are in the same boat, go the smaller size with Evoluent, provided you don't opt for the Anker. 1. Size Evoluent (standard size) felt a bit too big for my hands. The cheap plastic is also very slippery, making it difficult to pick up the mouse and move it if you are at the edge of the mouse pad (and you do need a mouse pad with Evoluent). Anker fits my hand perfectly. I simply LOVE holding the mouse. It has a really nice rubbery matte finish that prevents your hand from slipping. 2. Hand Position Both Anker and Evoluent offer the handshake position. I would say that Evoluent hand position is about 80 degrees between table top and your wrist. For comparison, regular mouse would have your wrist at 0 degrees. Anker holds your wrist at about 65 degrees. It is debatable whether 80 or 65 degrees is better. With both mice I felt immediate relief of wrist tension. Going back to 0 degree traditional mouse position feels immediately awkward. It is a toss up between the Anker and Evoluent with a slight edge given to Evoluent, just because they have a bit of science in their product marketing. 3. Usability This is personal, but for me Anker wins hands down in this category. Anker feels intuitive right out the box. You click with left finger and right click with the right. The back/forward thumb buttons were also very intuitive for me. This is similar to most Logitech mice. Mouse buttons on Anker have nice rigidity to them. Evoluent, on the other hand, takes some getting used to. It is a big clunky thing that slips out of your hand. Left finger does the left click. But it is, by default, you pinkie and ring-finger that do the right clicking. You can also reassign right click to the middle mouse button, but somehow it feels awkward and you keep pressing the default right click button anyway. Also, it is EXTREMELY easy to accidentally click on Evoluent. Buttons are cheap and plastic, and the scroll wheel is a complete joke. Granted, Anker's mouse wheel is not stellar, but it works well. I must have the newer batch, as I cannot relate to any of the scroll wheel problems mentioned in review. Don't forget Evoluent's back/forward mouse buttons. They are awkward to use at first, but you get accustomed to the arrangement. Matter of preference here. 4. Tracking Evoluent tracking is ABSOLUTELY TERRIBLE. I have a black Ikea Galant desk. It's not shiny, just wood with black matte veneer. Everything tracks on it....... except the Evoluent mouse. So you HAVE to get a mouse pad. And be careful, you won't get tracking on every mouse pad, even if it is matte black. This is on a $100+ mouse!!! On the other end of the spectrum, Anker tracks on everything except glass. This is a $20 mouse. In summary, there is not much to chose from in the vertical mouse arena. So get the Anker vertical mouse, get rid of wrist strain... and save Evoluent for the fanboys.

Received the mouse and after few days of usage realised the mouse has sharp edges near palm touching corner. I emailed customer service with images and they simply sent a new replacement. The mouse is a delight to use. Requires 2x AAA batteries (not included though :( ) . Coming from Microsoft Natural Ergonomic Desktop 7000 the mouse was a natural transition. The mouse is plastic but not a slippery one. As far as functionality is concerned, the mouse is a full sized one. My first finger fits perfectly while the second finger sometimes slips slightly below the right click. Overall, it is a must-have replacement for traditional mouse or for people who are not gamers. Size comparison is with Logitech G700s series.

After about 8 months of use with my Logitech MX Master ($100.00, price has since dropped), I started getting that all too familiar wrist pain. Especially on the outside of my hand and down the outside of my forearm. This mouse is a $20 dollar jewel. With its first use, the pain subsided substantially. I do believe the mouse could rotate the hand another 5 degrees to the right for better ergonomics, but it just might be because I am a large handed guy. 6'4", built like an NFL defensive back. It took no time to get my hands used to the position it was in as well as the button positions, which all felt natural. The mouse is fairly light, but not a feather, and the construction still feels sturdy and well built. It feels of some kind of rubberized plastic, I am sure there is a term for which I am not familiar. The mouse movements seem to have shorter throws than a typical mouse, as micro movements, such as having to click on a very particular area took a day to prefect. Mainly due to hand position, since your wrist is slightly turned upwards and too the right, certain movements, such as going to the left, now has a slight downward pull when done because it is now done with your wrist. As you can make more movements via the wrist than moving the entire arm due to the positioning of the hand. I own a few other Anker branded products and continually find that despite their typically cheap'er' price point, they are well made and engineered products. And possibly may have found my new "brand"

Amazing mouse. I have a weak base thumb as a result of three pregnancy swells and typing for work. I had to find something other than going to therapy weekly for the pain relief. I bought this after it made sense to me that the way you hold this mouse is like the relaxed hand position. I paired this with a slanted ergonomic keyboard and the pain is a lot less. I type extensively for work and I love this mouse. In the year that I've owned it, I've had to change the battery once. The cursor movement is real smooth and the side thumb buttons are super helpful.

Recent purchase so if my opinion changes this review will as well. This is my 2nd Anker Ergonomic mouse, my first one is a wired version for work, this wireless version I purchased for my laptop because I've found after using my wired mouse, I absolutely can't stand any other kind- to the point where I don't understand why the majority of people still use a standard mouse. This mouse is so natural to use, and it really does make a difference- it's really weird to say but I actually ENJOY mousing now. I use 6 screens at work and unfortunately the programs I use require a LOT of mouse use. This mouse at work has completely gotten rid of any weird feelings or pain I used to get in the tendons/muscles of my hand that I used to get with a traditional mouse. Carpal tunnel is a real danger in my job and I truly feel that this mouse will definitely quell or prevent that possibility from happening- at least as far as mousing goes. That being said, this wireless mouse is easy to plug and play and is otherwise exactly like my wired mouse as far as use and size. I see some complaints about battery life so I'll be sure to keep an eye on that for myself. I have a laptop with windows 10, and had no issues with it working right away. On the subject of size which may be an issue for some, I have a fairly long, slender hand, from the tip of my index to the bottom of my palm almost 7.5". I wouldn't change a thing about this mouse for my hand size it is perfect. I also have a coworker who purchased this mouse (wired, for work) after seeing mine- she has a smaller, thicker hand and she loves her mouse as well. I would say, if this particular ergonomic mouse doesn't work for you, keep trying to find one similar or that works for you, because in my opinion, unless you use a mouse very little, a traditional mouse is definitely NOT the way to go. Just because that's the way we've always done it, doesn't mean there isn't a better way.

I bought this mouse because i have wrist and lower arm pain. I can't actively use any regular mouse more than 1h at a time, without getting some pain. Made the switch to a trackball mouse (logitech M570), which was an improvement, but i still had some pains, from the wrist angle (which was not much different from a regular mouse) and from the tendon that belongs to the thumb (since the thumb does all the hard work on this particular mouse). And besides, cleaning the ball every now and then became a chore and it wasn't that precise (esp for games). So i wanted something else, and since only vertical mice were left to try, i bought this one, since it had positive reviews and looked good from the pictures. The good: + it's comfortable, and this is the most important thing, because so far i can use it for hours and don't have any pains. The wrist isn't twisted like on a regular mouse and i can feel this, for the better. Took me under a day to get adjusted to this angle. An interesting thing about this design is that you feel more inclined to use your whole arm to make mouse movements, which is a good thing, since doing so puts less stress on the wrist. This goes well with the lowest dpi setting, at least in my case. + i love the placement of the back and forward buttons, on the top of the thumb, where i can access them easily. + the construction is very good, on par with much expensive mice (Logitech, Razer -which i've used in the past, since i'm also a gamer). The plastic doesn't cracks when i apply pressure, it's as solid as it can be. But it's also light, for a wireless mouse (i've had heavier, from Logitech). The paint is a silky rubbery stuff, like the paint on Razer mice and some Logitechs. We shall see how much it lasts without peeling (a problem which i had with one Razer mouse). + the buttons don't wobble and the clicks are solid (maybe too solid). + the tracking is incredible, i've tried everything from bed sheets, blanket, jeans to wood and rubbery plastic, it tracked without issues. Only on glass it didn't work, but that's expected. Impressive. + it has 3 DPI settings and one blue LED that blinks for every dpi setting. + the mouse scroll wheel is pretty good, doesn't wobble much and is relatively quiet. + it looks very good on the desk, very stylish, modern design. All other vertical mice that i've seen looked like something from the '90s. + the battery life is very good, used it heavily for a week and still works. Works with 2 AAA batteries (not included), i've used two rechargeable Eneloops in mine. No problems. + fits well in my average man hand (i have 7.5" measured from wrist to the tip of my middle finger). + the wireless works good, even from 7-8 feet (i use it plugged in the back of my desktop pc, but i can move it to the front, if needed). I don't feel any input lag from the connection, so i can also use it for games (a big plus for me). If you have problems with the reception, you could try another USB port or move it closer, with a usb extension cable. Not needed in my case, but wireless can be tricky in some configurations. YMMV. The bad: - also the general size is good for my hand, my pinky remains on the mouse pad if my hand is relaxed. It has room to sit, barely, but only if i grab the mouse completely and firmly. If not, it drags on the mouse pad. I really wish the mouse shape had a support there for the pinky finger. I can get used to it, but it's an annoyance nonetheless. - the clicks require more force than needed, especially for a mouse that's designed to alleviate RSI and such. The middle scroll button is even harder to press. Mind you, this isn't something out of the ordinary in the computer mice world, but for an ergonomic mouse, this should be fixed (at least the middle scroll button). Other thoughts: Be careful when you move your hand to grab the mouse, coming from the keyboard area. Since it's much taller than a regular mouse, you risk hitting it by accident and throwing it on the floor. The funny thing is this requires more time to adjust than it takes to adjust to the vertical shape. The mouse enters a sleep mode after a period of 4-7 minutes of inactivity. You need to press a button to wake it up. Moving it around won't work. Doesn't bothers me, but you should know this. 1 year later UPDATE: it held up well, the rubbery paint is still intact (though it attracts oily fingerprints) and everything else is ok. Also, though i've said i'm a gamer, i didn't said i'm a pro gamer. But as i mentioned earlier, i don't notice any input lag with its wireless reception, but the lift off distance of the sensor is a bit higher than on other gaming mice i had; this may or may not bother you. If you don't know what lift off distance is, then don't worry about it. :)

Right after leaving my review, I was contacted by Anker customer support to inquire about my issue and provide me with an alternate solution. I opted to go with a replacement mouse. It arrived in better packaging than the original mouse so + points for that. I have been using the new mouse for over a week now and so far I have not had any issues like the original mouse. I will update my review again if the problem comes back. I would like to give major props to Anker for having world class customer support. Customer support person I was communicating with, was very quick in replying my messages and provided me with a replacement within a couple of days. Now that's what I call outstanding. For that purpose, I am editing my review and giving it 5-stars because no product is perfect and some items are bound to be bad but when you know that you are in good hands it just gives you confidence to go back and try the products from same manufaturer again. Kudos to Anker. ** Original Review - 3 star rating ** From functional stand point, it works. I was having wrist pains and using this did help. But it takes some getting used to. However my biggest complaint about this mouse is that after a few months of usage, its scroll wheel is not working correctly. Scrolling is either missed completely or when it works it makes the pages jump up and down during scrolling. I have stopped using this mouse and went back to my older mouse.

This is the most comfortable mouse EVER. The pictures are deceptive. It accommodates your hand in a completely natural position, without twisting your wrist around like a standard mouse.TRULY ergonomic. It's logical and intuitive in operation.There's no learning curve in trying to get your hand used to it. Extra buttons, which you don't have any trouble figuring out! I don't know if they make these left-handed---I use right-handed--but there are more buttons than you have on a standard mouse, and more functionality, so you save a lot of time. You don't have to remove your hand from the mouse to do something on the keyboard, or waste your time trying to get to the back button on the screen, or example. The buttons will surprise you, too, until you get to know them... best way to describe it is something like you finger DISCOVERING the mouse functions, like "Oh! There.. ANOTHER button, that is SO COOL." Or "Rrrighttt. The scroll wheel is PERFECT for this." The main downside is that any other mouse will make you grumpy by comparison. It functions like it should cost much more than it does. I didn't remember that I'd bought this here--for some reason I thought that I'd just gotten lucky, and that I'd purchased it blindly at our school fundraiser--and, sadly, I thought that there would be no point in finding it again, but I thought I shouldn't be throwing my money at more fancy ergo mice. Don't waste your money on a cheaper, semi-ergo mouse. This is the one. Also: Wireless, so it's not messy, and you don't have to worry about getting it tangled. OPTICAL. Seriously. Just easier.

First, I want to say that if you have never owned an Anker product or are unfamiliar with the brand in general, do yourself a favor and leave a mental note to give them a try. I discovered them last year when I was tired of cheap charging cords lasting a week or two. I did a little research and decided to try a premium quality cord for once to see if there was a difference. Not to sound over dramatic, but I couldn't believe the difference. I'm still using that cord (which is an Anker Powerline+ btw) to this day and it still feels and looks brand new. That first experience stuck with me and Anker is slowly becoming my go-to brand for anything electronic related. This mouse is my 6th Anker product. And they are all great, this mouse is no exception. It is very well made. It is large and feels substantial in the hand. The entire mouse has a soft rubberized coating that feels great. The movement is butter smooth and responsive. The buttons have a satisfyingly clean & crisp break and a nice snappy audible "click" when pushed. The scroll wheel spins with the perfect amount of resistance and that "racheting" incremental movement. The vertical position feels natural and comfortable even through extended hours of use. I can't think of anything I would change about this mouse or any other Anker products I've used.

Update: 5/14 Anker sent me a replacement and after testing for a few days, the new mouse has none of the problems for my original review. The mouse works just like the first one I purchased from them, without the mouse buttons getting stuck. Perfect product. Old review: I might've just gotten a flawed product with my second purchase. I'll be quick about this review: The mouse is good. I like it alot and want to use it in the future should this one dies. I've used a vertical mouse at work and at home for nearly 4 years now so my hand is used to the grip and movement. My wrist pain pretty much entirely disappeared. I've found this mouse to be perfect for my wrist as some others are too vertical and others barely make a difference. That's why I repurchased this mouse when my first one died. The problem I found with the Anker AK-UBA Vert Mouse is the consistency of the left and right mouse buttons (LMB and RMB). I've owned 2 of these so far. The first mouse's clicks were perfect. This current one I just bought sticks sometimes. Holding the RMB and clicking the LMB can sometimes cause the button to stick and cause issues. Imagine playing a game and having this happen randomly whenever you aim and shoot. My first mouse never had this issue. The wheel click also sometimes activates while casually scrolling up or down. Overly sensitive? The mouse reads my desk well enough and isn't oversensitive so I love it. The grip is a little slippery so I just use anti-slip stickers to help me keep grip and not launch my mouse across the room. I am extra conscious now about my clicks to try and avoid it sticking, but in the future, I hope this won't be a repeat issue. Note: My first mouse pretty much just stopped working after 3 years. Didn't light up at all, even with new batteries and just wouldn't turn on again. For the price and how it's the perfect angle for my personal setup and my wrist, I'll still rebuy.
