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 Mike Hernandez

After developing a repetitive stress injury, I gave some serious thought to my mouse. I rely on my computer for both my job and my hobbies, so I don't want to lose the ability to use it. This mouse seemed like a great solution. And it came in my favorite color!And I was right. This mouse relieved a lot of stress from my wrist and thumb. It didn't take long to get used to the new position. I wouldn't consider it the most ideal mouse for gaming, but I was able to make it work.But my first red flag came after a month of use when the first round of batteries died. Ok, maybe I just grabbed some old batteries by mistake. But, after come confirmed new batteries, another month later, and I'm changing them again. But the real kicker was when I transferred some files using a usb drive. My mouse receiver is plugged into the front USB because I needed a bit more range. But when I plugged in my drive to transfer files, something happened to the wireless range. Basically, it wasn't able to operate in its usual position (which led to a different kind of discomfort.The design is great. I really love it. But if the mouse doesn't mouse, it's pretty useless. I'm now in the market for a new one.
