The MKETech 604 Ergonomic mouse is either perfect for your hands, or almost perfect. Some say it takes a little time getting used to it, but ergonomic lovers know, once you fall down the deep ergonomic well, no other water tastes as good, or in other words, give it a few days and you'll get it. Lightweight, wireless, adjustable DPI, shortcuts for side scrolling, task switching, and zooming, what else do you really need? Nothing. This has it all, and nothing extra. Save your wrists for the things you love.
