There was a problem filtering reviews right now. Please try again later.
My conclusion is that you just can't judge how a mouse will fit you from reviews. Even reviewers with small hands like mine, had opinions I wholly disagreed with. And I think it's because people use the mouse in a variety of ways. For example, some people rest their hand entirely on their mouse while others use a "floating" hand. Some anchor their wrist and move their hand, while others anchor their elbow and move their forearm. Some have small hands; but, wrist pads and wrist braces raise the wrist, cancelling the problem of (or even overcompensating for) small hands.
Especially if you're like me and rest the entire weight of your hand and also anchor your wrist, you're not going to be happy with *any* vertical mouse *at first*, because your hand will feel like it's sagging down the mouse, and when you try to unsag your hand the mouse will feel insecure because you're unanchored your wrist. (This is where the cushion of a wrist brace helped immensely. After 2 weeks I was able to use the mouse even without the wrist brace. But man, did I hate all 5 mouses at first.)
Anyway, moral of the story: Bite the bullet and purchase a few mouses. $150 gets you 1 quality mouse and 1 or 2 cheaper ones.
Here's a wrist brace I love because it's not plastic-stiff (no affiliation whatsoever): https://www.amazon.com/gp/product/B072392YGD.

- There's a reason I didn't try the famous Evoluent VM4R. The updated model is getting flack for not living up to its predecessor, and its predecessor apparently hasn't shipped a driver for Mac OSX Catalina, which is what I'm on.
- The Anker and Lekvey have exactly the same chassis (and therefore size). The Anker is battery powered while the Levkey is charged. The VicTsing is slightly larger than those. The Jelly Comb is significantly smaller than any of them.

I used the mouse for a few weeks and here are my thoughts. Glides really nice on the desk. No need for a mouse pad. Don’t know what the DPI button does. I see no difference in the motion or movement of the mouse at all. If it didn’t have this feature, I wouldn’t miss it. The up & down buttons for web browsing is a nice feature but found it to be a little uncomfortable to use. Another feature I wouldn’t miss.
I have a problem with carpal tunnel & using a flat mouse every day for work has been causing a lot of pain in my hand. I was very excited to use the Anker vertical mouse thinking it would help, but it didn’t. Here’s what I feel is wrong. Though the wrist & thumb are no longer lying flat, the hand position is the same as a flat mouse. I would have liked my hand to lay more vertical. The issue I’m finding is this. With the flat mouse, in order to use the left/right button, you just press with your fore finger and middle finger. There is no pressure on the thumb at all because the mouse is lying flat on the desk. With this mouse, you need to use your thumb to hold the mouse steady while using the right/left button. This causes some pressure on the thumb and grip. May not seem like a big deal, but after hours of use, my hand was aching. This mouse is also much wider than the mouse I was using and it’s putting a strain on my hand. Wish I did like it better cause I love the vertical concept
1. Claw grip: my preference for mice has always been a palm grip because it feels natural. But as I explained above, the mouse is slippery. To get around this I have to claw the mouse and even then I still have to hold my wrist in an unnatural position.
2. Double up: I have always used one finger on the left clicker and one on the right. But to prevent my fingers from hanging off the edge of the mouse I have to rest two fingers on the left clicker. This method is more comfortable but I do find myself accidentally right clicking when I try to use the scroll wheel (maybe I'll get used to it).
All in all, the mouse works great but the lack of a pinky rest, along with the point near the dpi button, makes using the mouse uncomfortable.
One final note: the mouse has a convenient slot underneath, so you can store the usb dongle.
UPDATE & COMPARISON: I added one star for the awesome customer service.
A few days after I wrote my review I was contacted by customer service and they offered to let me try the new model (Wireless Mouse, Anker Ergonomic USB 2.4G Wireless Vertical Mouse with 3 Adjustable DPI Levels 800 / 1200 / 1600 and Side Controls, Black). There are some differences/similarities between the two which I will list below.
1. Left/Right Click: The new model requires slightly less force to click - likely because it isn't as "vertical" as the older model - but the difference is really insignificant.
2. Scroll Wheel: I'm tempted to say that both models have the exact same scroll wheel with different mounting, and there is one minor as well as one huge difference. The minor difference is that on the new model the wheel is sunken deeper into the mouse than the old model (this can be seen in the pictures I've uploaded). The huge difference is that the scroll wheel on the old model requires a lot more force to click compared to the new model. Using the old model I often found myself missing or accidentally scrolling when I tried to press the scroll wheel, but on the new model it's very natural.
3. DPI Switch: For both placement and button quality, the old model surpasses the new model. On the old model, using the DPI only requires you to slide your thumb up (and the button is impossible to miss), while the new model is a tiny button behind scroll wheel. This shouldn't be a problem unless you're constantly using the switch.
4. Forward/Back Buttons: These are completely different on the two devices. In terms of responsive they are, the buttons on the new model can't even be compared to the old model. It only takes a very light pressure to use them - it's so easy you can click the forward button with the tip of your thumb and the back button with your inner thumb knuckle without even trying. On the other hand, the new model requires more force but it isn't "too much" force, so you don't have to mind the buttons if your thumb is resting on them and you don't have to try too hard to press them.
** This may just be the item that I received so I've "starred" this difference. The back button on the new model feels flimsy and ready to break. It feels like there is some kind of spring pushing up on the button, but that spring is off center such that one side can be depressed much further than the other. This gives the button a "cheap" feeling.
5. Shape: As someone who'd much rather rest their hand on their mouse as opposed to holding their hand in a certain position, the new model's shape dominates the old model's. Honestly, it's because the new model doesn't have the pointy edge. Without the pointy edge there are much more ways to hold the mouse so it's easy to find a comfortable position. That being said, the new model is also slippery and doesn't have a pinky rest (disappointing), but it's still much more comfortable than the old model.
6: Size: The mice are roughly the same size, but because of their shapes, the new model "feels" smaller in my hand.
UPDATE #2:
I ordered the first mouse on December 3, 2016 and I'm not sure when I received the replacement. As of today (05/07/2018) my scroll wheel has officially stopped working. I'll scroll down and it moves down a few units, then back up a few units. Everything else works great, but without a scroll wheel it's useless for me. That being said, the lifespan of this mouse seems to be just over a year.

J'ai voulu tester une souris verticale, et celle-ci me permettait de me faire une idée à bas coût.
Les plus :
- La prise en main est déroutante au début, mais on s'y fait après quelques heures d'utilisation.
- Une fois qu'on a la souris bien en main, on sent bien que la position de notre poignet et bien plus reposante.
- Il est possible de ranger le dongle sous la souris, ce qui est très pratique.
- Le bouton au dessus de la souris permet de changer la sensibilité (dpi) de la souris à la volée.
Les moins :
- La souris ne respire pas la qualité. Après seulement un mois d'utilisation le revêtement commence à disparaître.
- Le bouton de la molette est assez dur. Mais on peu cliquer en relevant le majeur et en cliquant sur le côté. Avec le temps cela s'améliore.
- Le bouton de mise en marche est très dur également, cependant avec le temps il s'adoucit.
- Pas du tout adapté au gaming. Le capteur n'est pas de qualité et elle a une certaine latence. Cela dit, elle convient parfaitement pour de la bureautique
Conclusion :
Si vous possédez un meilleur budget, je vous conseil plutôt de vous tourner vers la MX Vertical. Cependant, cette souris mérite ses 4 étoiles et Anker à le mérite de proposer une souris ergonomique sans fil à bas prix, ce qui permet de se donner une idée.
Si vous trouvez cet avis utile, pensez à cliquer sur oui. Cela fait toujours plaisir de savoir qu'on a pu aider quelqu'un.

People in the office say it feels weird but I don't notice anymore (had it over a year now) and it only took me a few moments (seconds) to get used to it, it was couple of days before I stopped knock it over moving my hand around. Works just like a normal mouse but your hand is turn to a more natural position. Think about it put your hands out in front of you with you elbows by your side, what way does you hands what to be? now think of how you hold a normal mouse.
The 3 dpi setting are great and match the cheap gaming mouses, I have gamed once on it when I got it was fine no issues. But if you big into gaming stick with your gaming mouse for gaming and this for other things that what I do.
Battery life is great I get a couple of months using it 8 and half hours 5 day a week. there is an on/off switch on it but I honestly never use it, it powers down after a few min of no use and you just need to click any button to get it going again.
Just encase anyone wonders there is a spot under it for the Bluetooth when not in use.
It hasn't started to even show ware a year later. I love this thing and would buy it again in a heart beat.

That puts Anker in prime position to target options-limited consumers with devices that either:
A- were not thoroughly tested
B- were great designs, ruined by committee rule or a "looks first" approach.
I'm thinking B, because the build quality is otherwise stunning, especially at this price point!
If you try to close a door from the edge nearest the hinge, it's hard work. That's how clicking feels.
In a quest to have clean lines that join up, Anker has opted to go with a single piece of flexible plastic for Left/Right click. This has no give until about an inch and a half from the "hinge"
The "central vertical colum" extends too far back into the area between your thumb and forefinger too, so even with adult male hands, it's awkard to click near the softest part.
Long story short, your thumb "braces" to counter the force slightly and it starts to cause problems after a while.
(And that's with me switching to a regular mouse every so often to give my hand a break)
The browser back/forward buttons also feel tacked on at the last minutes and take some acrobatics to operate, but at least being difficult to click makes them impossible to accidentally click.
There's so much right with this mouse:
-great tracking, some of the best even
-glide pads underneath are super easy to clean and really well adhered to the base
-the single battery lasts ages
-the plastic finish feels gorgeous to the touch
-there's a little low battery light under the back/forward buttons.
-scrolling is great, feels really good
-perfect weight
In either scenario, I can't really see how this was missed in a product which otherwise easily the best I've used in the last 30 years. And that's a warning bell that something's really not right at Anker.

For me it was also working overtime so I could be doing 10-12 hour days at a computer. My wrist started to feel 'weak' and I couldn't grip things very well - like my steering wheel. It would always feel better at the start of the next day so I didn't think much of it. Then it stopped feeling better and I constantly had a weak, numbing feeling in my hand and wrist. I was starting to overcompensate with my left hand, it was badly affecting my everyday life.
So I googled and found out about the vertical mouse. Quick look on Amazon and this one came up as a sponsored link, but due to the low price and excellent reviews I bought it. Next day delivery, on a Sunday too.
I've been using this for a month now but I can honestly say I felt the difference the very first day. It takes a few minutes to get used to holding it but now it's second nature. Before trying this I was extremely stressed trying to work though the pain. I had got to the point where I was crying on the drive home thinking I would have to leave a job I loved because I was losing feeling in my hand.
I would advise that you buy one of these regardless of if you have wrist issues - why wait until you're in pain. All I can say is for the price what have you got to lose?

The mouse is far too light. I don't understand the trend with making mice as light as possible - surely with some resistance this allows for finer control? I also found that having to click the mouse to get it to wake up started to become annoying - there is no indication whether it's awake or asleep until you try and use it.
It had since been replaced with a Microsoft Sculpt Ergonomic Mouse, which has a near-perfect amount of resistance.
