I'm a software engineer and ignored wrist and forearm pain for almost a decade. Finally it got really bad so I had to take some steps to improve my condition. I purchased 5 vertical mouses, 1 of the more expensive ones and 4 cheaper ones, to see how they compare.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.Here are the products I compared:- https://www.amazon.com/gp/product/B073B12MS6 (Jelly Comb)- https://www.amazon.com/gp/product/B07RK96WF8 (VicTsing)- https://www.amazon.com/gp/product/B00BIFNTMC (Anker)- https://www.amazon.com/gp/product/B07BFCVJZC (Lekvey)- https://www.amazon.com/gp/product/B07FNJB8TT (Logitech MX)Miscellaenous:- There's a reason I didn't try the famous Evoluent VM4R.

I'm building a work from home setup for my wife with 34" Ultrawide LG monitor running macbook pro in closed display mode. We were using Apple Magic Mouse but we noticed alot of stress to the arm and decided to buy an ergonomic mouse. I bought four mice all together : Anker B2C, 2 of the Jellycomb (MV045 & MV09D) and iClever TM209G to compare. Out of the 4 mice, this iClever mice was the last one to come out of the box for the test and honestly I was kind of bummed out only to find out the same exact Jelly Comb MV045 mouse inside the box just with different branding. The iClever didn't have bluetooth where as the Jellycomb did. I honestly didn't even try setting this one up as the form factor was rather uncomfortable for us. Here's the deal, you get what you pay for. All mice performed a good job. Fairly easy to connect with included usb dongle. However, the cheaper jellycomb kept disconnecting when connecting using the dongle. Fortunately it also has bluetooth mode and the connection was much better. I prefer bluetooth over the usb dongle because the dongle takes one more usb port that could be available for other devices on my Caldigit Soho USB C Docking station! Anker mouse lacks bluetooth but I didn't have any issue with its wireless connection using the dongle.
