I was pleasantly surprised. I had purchased some of the smaller mice before and they cord started pulling out from the mouse in no time. These seem to be holding up much better. Very pleased with my purchase!
I got this mouse to keep in my computer case. Its thin profile is perfect, though it's on the small size for my hands. I chose wired over wireless because I don't want to be caught away from home with dead batteries as often happens with my wireless mice.
