Review on Memzuoix Wireless Ergonomic Mouse, Upgraded 2.4G Optical Cordless Mice With 800 / 1200 /1600 DPI, Vertical Computer Wireless Mouse For Laptop, Mac, PC, Desktop (For Right Hand, Large), Black by Stephen Cooper

I bought this mouse just over a year ago as I was concerned with being on a computer all day for my accounting work. I could tell I was getting early signs of carpal tunnel so I decided to search for a vertical mouse. I have been using this mouse every day since and it has been amazing. Comfortable, works just fine. No defects whatsoever. I would say it is durable as well considering it has lasted this long. No issues with scrolling or lagging effects. I got exactly what I was looking for.
