Review: Perfect - A perfect mouse for multiple device use, and switching is easier within devices. Very comfortable to use.
Review: FRUSTATING SCROLL INPUT AND INTENTLY DEFECTIVE PRODUCT - Inherently defective scrolling input and scroll wheel and this directly leads to unusability, after few days the scroll become jittery than starts registering opposite scroll inputs to what you give than altogether becomes frustatingly unusable. I returned even though i got a better deal of 3650 instead of usual price of 4100
