This mouse is a light weight, no frills mouse that fits both left and right-handed mouse users equally well. While the mouse initially felt a bit narrow (it's about 2-1/4 inches wide) compared to my old, Logitech mouse, I quickly became comfortable with this form factor. The pressure applied to activate the mouse buttons seem right with no false mouse click resulting from my fingers resting on the mouse while navigating - just as it should be. Tracking seem smooth while used on a mouse pad. (I cannot comment on how this mouse performs on a solid, desktop-like surface because I never use my mouse in that manner.) As for long term reliability, I can only say that it has perform as expected in the 1-1/2 weeks I have owned it. I am a business/engineering class mouse user and do not used my mouse for gaming. If you are looking for a capable, budget class mouse, this might be what you are looking for.
