EvoluentVerticalMouse D - Right handed USB wireless - Medium

My wife had an old Size Small Evoluent 4 mouse I had used for a few years, she got it through an Ergonomic assesment...I started having forearm (carple tunnel) pain flare up. The vertical mouse fixed that...however a small drawback was that my pinky/bottom side of my hand would get sore by the end of the day.The buttons finally crapped out on that old mouse so I finally replaced it with this one (Evoluent VMDL 'D' ) in a Size LARGE!!! For AutoCAD (drafting primarily)...btw I have Men's medium hands (Size 9 gloves) and love the Large Size Fit...not sure why I waited so long to get the right size...worth the ~$150 CAD I paid. Would Buy Again...and love the Chrome look over the old Blue-ish/Purple. My pinky/side of hand pain/numbness is completely gone...would recommend to all who mouse all-day producing DWGs and etc... Evoluent should make a size XL for men with even larger hands!

This is the most comfortable vertical mouse I have tried. It holds your hand the most sideways, which is very important for eliminating lateral wrist motion. I tried a cheaper vertical mouse and returned it before coming back to Evoluent, man it was not even close. You don't have to twist your arm, pinch your fingers, make any weird motions, your hand just sits there. Compared to other mice this one is like AHH so natural. I LOVE having 3 finger buttons, being able to use middle click for opening links or pasting (usually the mouse wheel click on a normal mouse). Mouse wheel can also scroll horizontally while holding down one of the thumb buttons. I never knew I needed these two features in a mouse but I now use them constantly. The Evoluent software (Windows only?) allows you to remap the buttons for many additional functions.One change from the older model Vertical Mouse 4 I do not necessarily like is they have made the 3rd mouse button smaller. This is the button you press with your ring finger, whereas on the previous model it was pressed with your ring and pinky finger, definitely easier. I cannot comment on the battery life, this is my first wireless version and it has not run out yet. It takes 1 AA battery.Pros:Most comfortable vertical mouse available (this is #1)Lots of additional functions for common activities.Contoured finger buttons feel nice.Includes battery (!!) and extension cord for the wireless receiver (I have not needed to use it so far)Looks cool (better than in the picture), feels more premium compared to old model, more on par with mice at this price point.Cons:ExpensiveMouse button 3 harder to press than the Vertical Mouse 4 now that you can't use two fingers.

Compré este mouse porque se me diagnosticó Quervain. Llevo usándolo una semana, ocho horas diarias o más por mi trabajo. Debo decir que me ha funcionado de maravilla. es más cómodo y me ha ayudado en mi lesión. PERO primero hay que acostumbrarse sobre todo si nunca se han usado este tipo de mouse. Segundo, hay que buscar varias posiciones, alturas, etc. En mi caso, no me acomodó perfecto hasta que no puse una superficie donde elevar y descansar mi brazo. Una vez hecho esto, encontré la posición ideal. Entonces hay que buscarle antes de juzgar que no sirve.

Fits my small right hand. Does the job!

In terms of comfort and its ergonomic shape this is by far the best mouse I have ever used. My hands are big, but I ordered the medium model, which turned out to be almost insanely comfortable. I lucked out by ordering an open box item, which saved me a cool $70, not bad at all. And it was delivered in two days! Even with no discount this mouse is totally worth it, especially if you really want to avoid wrist and arm pains. The only caveat, and a major one, is software. My main workstation is a Mac. In order to take full advantage of the buttons you need the driver. Sadly, Apple has not yet provided the maker with the necessary driver development kit for MacOS 10.15 or newer. Earlier versions of the driver are not compatible with MacOS 10.15 or 11. This makes life more complicated because without the driver the buttons default to the developer setup, which I find weird: for instance, the wheel does not work like the standard wheel, but as a Forward button, and the right button works like the standard wheel! This is, apparently, more convenient - not for me though. I want the wheel to be the wheel, and the right button to be the right button. As well, although the thumb buttons are extremely conveniently placed, the lower one does nothing without the driver! I repeat: if you use a Mac these settings are impossible to change without the appropriately coded driver software. Luckily, the manufacturer provides a link to third party universal driver, namely USB Overdrive, which enables you to change the settings. Sadly, USB Overdrive is not as intuitive as one would wish for. It took me a while to figure it out and set up the buttons the way I like it. Additionally, USB Overdrive takes over almost every non-Apple keyboard and makes it impossible to use without deleting everything, that appears below 'Z Axis down' under the Settings tab, 'Any Mouse, Any Application' option. If you venture to use this universal driver, you will immediately know what I am talking about. I trust Windows users will not have these problems; I have not yet checked the mouse on my Windows machine, but the driver for Windows 10 is available from the manufacturer and I believe it should work under Windows 11. Other than that this mouse is awesome, simply amazing. Over the years I have tried many ergonomic mice and none made me as happy as this one. If you are a Mac user and not afraid to try USB Overdrive (hopefully the manufacturer will finally offer drivers for MacOS 11 and 12), then you will be a very happy camper. IMHO this is the best ergonomic mouse on the market, period.
