Evoluent VMDMW Vertical Mouse 4 for Right Hand – Ergonomic Mouse Wireless USB, Helps Reduce Carpal Tunnel, Adjustable Speed & Programmable Buttons, Vertical Ergonomic Wired Mouse, Gaming & Office Use

It has a middle click which is not present in most vertical mouse. Very wrist friendly, best mouse I ever used.

GREAT DOING WHAT IT SUPPOSE TO, BUT WAY OVER PRICED!

I don't usually leave reviews, but this mouse is ergonomically great for my hand and probably the best choice for wired users. This is why I bought it in the first place—to be able to use a wired mouse that didn't hurt my hand. One caveat is that it might not work on all mouse pads. Other than that, it's comfortable, which is what I wanted. I've only been using it for about a week, but it's good enough to leave a review to help someone else find what they're looking for. It's worth the price. I have to comment on my wireless Logitech MX 2. I love that mouse for wireless use, but there's no wired version. I'm loving this mouse for my wired solution; it's great.

To start with, I've tried many different designs of ergonomic mice, and vertical mouse designs are by far my favourite and this Evoluent mouse is my favourite among the vertical mouse designs. It's almost a 90 degree tilt so my wrist isn't pronated at all while using it, which is important as I work a desk job and am on the computer for 8+ hours a day. It also fits into my hand extremely well. The pinky rest it has is also an under appreciated addition that many vertical mice do not have, it keeps your pinky from sliding across the desk as you use the mouse. I also really like the functionality of the 6 different buttons you have access to. The default options work great, though it's also nice that there is the option to remap the buttons with the Evoluent mouse driver. The battery life is more than adequate, I only need to swap batteries once every 3-4 weeks (if that) and I have a set of rechargeable batteries on rotation. It's also very easy to use, just plug in the dongle and it should work right away (if you're coming from a "normal" mouse, the adjustment to a vertical mouse might take you a bit to get used to), though you can also install the Evoluent driver to make the mouse more customizable.That said, it's not a perfect mouse. I think the materials used in the mouse could be of higher quality to increase the durability of the mouse. This is my second Evoluent mouse after the first one broke after roughly a year and a half of usage. Also, the exterior of the mouse is a high gloss plastic, which, although it looks nice, can actually make gripping the mouse without your hand sliding around a bit difficult, especially for people like me who have naturally sweaty hands. That said, a simple solution to this is to take some sandpaper to the glossy plastic and rough up the exterior of the mouse. It dramatically improves the grip.If I were to suggest any changes, it would be to make the mouse (or a new edition of the mouse) with higher quality materials, offer an alternative exterior material that has much more grip to it, and extend the pinky rest to wrap around and offer a palm rest as well.Despite these drawbacks, as I said earlier, this is easily my favourite mouse. I already mentioned that I'm on my second one and I will continue to get Evoluent mice because their ergonomics are just perfect for me.

While I really like the ergonomic design of this mouse (5 out 5 stars) and it solves my carpal tunnel syndrome, it does have some fatal flaws. I'm now on my 3rd or 4th mouse in the last 7-8 years and because of frustration I'm giving this a 1 star review. It seems that the company has stopped innovating and I'm looking for another ergonomic mouse manufacturer. I really hate to do this as I'm now very comfortable and used to the ergonomic shape of this mouse but its not a cheap mouse and I cannot keep replacing this every year or so.FATAL FLAW: My main issue with this mouse is the left click seems to get stuck and stops working intermittently (in which case I tend to start using the middle click as my left click). Infact this has happened with all my evoluent verticalmouse over time. And I have trained myself to use the middle click as left click. Eventually even the middle click will either start to double click randomly or simply stop working making the mouse virtually useless.Other flaws but not deal breakers:The mouse precision is not great. You will find it hard to use it for precision drawing or gaming.The mouse sensitivity is also not very finely tunable. The software that comes with it doesn't allow for fine adjustments. Using the native windows mouse control panel doesnt help much.The mouse tends to use up the battery really fast, they generally only last 3 months.The usb receiver signal with the mouse is easily interfered. An issue I have never had with another other mice before. To make it work, I have to put it at the front usb port on my desktop. If I put another flash drive or anything else in the adjacent port, the signal to the mouse gets disrupted and the mouse can no longer be used properly. This is baffling since no such thing happens to any of my logitech or microsoft mouse.
