Anker 2.4G Wireless Vertical Ergonomic Optical Mouse for Work, Multi-Device Connectivity, 800/1200 /1600 DPI, 5 Buttons for Laptop, Desktop, PC, MacBook - BlackECOLOGO

Works Great - very comfortable. I have a few issues with my right hand, need carpal tunnel surgery and had broken my wrist playing football over 30 years ago and am pretty sure arthritis is involved now so there is a lot going on there. A traditional mouse was getting more and more uncomfortable, especially with the wrist action involved. This mouse has helped alleviate alot of the discomfort. 👍 Still getting used to the movement and precision needed for some tasks but it is a good mouse !!

I bought this mouse because I was having pain in my arm from using a regular mouse. The pain in my arm has completely gone away. There is a little bit of a learning curve just because your hand is in a different position. This mouse allows your hand and arm to be in a more natural position so there is no strain on your arm. The purchase arrived quickly and on the date it was promised.

I needed an ergonomic mouse but didn't want to foot the bill for an expensive one (or wait weeks for my employer to purchase one for me). This model was the right price and shipped free overnight (free with Prime membership). Within 2 days of use I noticed my wrist pain disappear and was very happy.I have small hands (5"L x 3-1/2"W) and this mouse fits perfectly. Good speed and reaction time for the work I do (lots of spreadsheets, graphs and emails). Button click and roller button noise levels are the same as any standard mouse. I don't use the forward/back buttons and sometimes I hit them with my thumb. Wish this feature could be turned off. Additionally, the device switch button is located near the thumb and I hit that often as well. The mouse has a smooth surface which feels nice but provides no grip so I find my thumb and hand sliding down. Due to the slipping I often find myself gripping the mouse with my thumb which causes pain after a long day of use.Overall, I am happy with the mouse but will probably add some grip material to keep my hand from slipping.PROS: easy to setup, smooth glide over desk pad surface, good fit for small hands, good reaction and speed.CONS: smooth surface allows hand to slip

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. SizeEvoluent (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 PositionBoth 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. UsabilityThis 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. TrackingEvoluent 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.
