Summary: -seems to cut out between 2-5 times per day -would not recommend for gaming but if you're ok with waiting 30seconds for it to work every once and awhile its a pretty good mouse all around
Pros: -bluetooth -extremely comfortable -responsive when working -great battery life -have not found a surface it doesn't work on. (used it on glass,black leather, jeans, black painted tables, brushed aluminum laptop finish, polished wood, and more.)
Cons: -takes a moment to wake from sleep -will randomly stop working and take up to a minute to start working again
Summary: Its very stiff that mouse wheel it is! Hard to turn and it felt as though the clicks were at twice the interval of a normal mouse and its slippery. Other than that, I really liked the mouse. It felt good in my hand and it seemed very accurate and free flowing.
Summary: Well made product, excellent smooth running and sensitive. One problem I have found though, and it may be the fault of Apple MacBook pro (Yosemite) is when the MBP drops to standby bluetooth communication is lost with the mouse and cannot be restored without rebooting.
