The RGB LED light flashing during operation is just mind blowing. The weight of the mouse is just perfect (additional weight also provided). The cursor movement and regitering every click is fabulous. The charge retention capacity is awesome, at l east 10 hours for a 15 mins charging. In terms of precision and accuracy it is unparallel - whether it is for gaming or every day use.
Personally I'm extremely pleased by the fells, look, sturdy built and performance of this mouse.
