I got these to replace an old Logitec wireless mouse that I had for many years. I wanted something more reactive (RBG lighting was a bonus). I like how I can charge it instead of looking for batteries. It has different lighting modes - it's cool. For example, how can I find my mouse in the dark as opposed to my old mouse? It seems to track movement in more detail, which is good for precision work. Maybe not for everyone, but I like the transparent design. The forward and backward buttons are conveniently located. Overall I am happy with my purchase.
