Review on 🖱️ ECHTPower Rechargeable Ergonomic Mouse: Wireless Vertical Mouse with Adjustable DPI, Reduce Wrist Pain - Perfect for Laptop, Computer, Desktop - Windows, Mac OS Compatible by Randy Brimmer

Pro: Very pleasant to use, good ergonomic shape. Very responsive, back/forward buttons are comfortable. Fast plug-and-play allows all buttons to be used (unlike other pointers that may require software) Cons: The surface is too smooth, the mouse is difficult to pick up and move quickly during use, it tends to to slide a little. No big deal, this is a gaming mouse so I suspect it gets stickier with age. No side scrolling with the scroll wheel. Not really important, but it was a feature on my last mouse that I relied on. There wasn't enough room for the little finger. i have big hands There isn't enough room between my ring finger and the table to hold the mouse naturally, so my pinky has to rest on the side of the table. Other vertical hands have a slightly higher base to allow for more room for the pinky. *UPDATE* After a few days of use, I started getting cramps and persistent pain in the side of my hand just below the base of my pinky. I believe this is because the shape of the mouse puts my thumb down too far, probably just not suited for my large hands. The feeling is similar to touching the tips of your thumb and pinky for a long time, which is not very comfortable.
