Review on 🖱️ Nulaxy Ergonomic Mouse - 2.4G Wireless Vertical Mouse with 3 Adjustable DPI (800 / 1200 /1600) - Optimum Ergonomic Optical Mouse with 6 Buttons - For Computer, Laptop, PC, iPad, Desktop, MacBook - Black by Erin Leuenberger

I spend 8-10 hours a day on the computer. I'm not new to mice, but I'm not familiar with upright mice. I am currently using a couple of large and very expensive mice. My wrist and arm get tired naturally, so I wanted to try the vertical one without spending a ton of money. I came across this guy and he was very cheap. So far I'm very impressed! Standard 2x AAA and a USB nano receiver that can be stored in the battery compartment if desired. Fit and finish feel very good, slightly rubbery. These guys have 6 buttons namely: left click and right click; has 3x levels to increase or decrease mouse sensitivity. I must say that it is quite natural to "grab" it and use it. I have a large hand size and it fits very well. The button placement is pretty good. The only thing I wish was there was more of a spinal line for my pinky to lean against, but that doesn't matter. All in all, if you're a fan or planning to try a vertical mouse, I don't think you can go wrong here!
