Like the performance, the weight, the size, the sensor, the cable of the mouse.
Had given this Excellent Review if I had reviewed it immediately after purchase when Logitech launched it.
Is back to my G502: a again.
The reason ?
Double-click when you're single-clicking, annoying when browsing or playing and having button bindings.
Seems to be related to the hardware of the mouse.
Tips for Logitech, add more money to component quality and less on RGB LED and other unnecessary bling.
Googled a little and is not directly lonely about the double-click problem.
Sadly, because it has the potential to be really good.
