Review on Memzuoix Ergonomic Mouse Wireless Mouse, 2.4G Large Vertical Mouse USB Optical Cordless Mice With 800 / 1200 /1600 DPI, Ergonomic Computer Mouse For Laptop, PC, Desktop (For Right Hand) Red by Robert Dabney

I was starting to get wrist pain in my dominant hand so I decided to order a vertical mouse to try and fix that. This was slightly cheaper than the Anker mouse at $20, so I went with this one. This mouse was plug and play for wireless which is great. The mouse clicks are in the right position and everything feels comfortable. I haven't tried it with gaming, but I can safely assume that it wouldn't perform as well in FPS games but most people aren't buying vertical mice to game. The rubber grip is the BEST part of the mouse as it secures your thumb in the perfect spot, and the Anker definitely did not have one by the looks of it. Overall I think it was a great decision to buy a vertical mouse and if you are looking for one too I would strongly recommend this one.EDIT: After 2 months my Wrist pain is completely gone so if I could give this 6 stars I would.
