1. Scroll Wheel: For many, as well as with me the scroll wheel now approximately 1 year is defective! It no longer scrolls up or flapping up and down. Short: When scrolling makes it what it wants !! I have read of people who therefore already exchange the mouse for the 3rd time! Googling times even after the term "Raptor Gaming M2 scroll" or "Raptor Gaming M2 scroll wheel"! The problem is known !!
2. Driver: Not reasonable and zero support or bugfix by the manufacturer or their homepage! Something I've never experienced ... googling times by itself, you will see how abkotzen all about the driver - even in the test reports !!
3. Sometimes when you want to click a sudden nothing works! The mouse is completely dead !! You then have to unplug the USB port and plug it back in, otherwise they are no longer going !! (Since no PC reboot! Helps) also a known problem that can "sometimes" dissolve but by switching the USB port.
Now I ask you: What time are we living ?? So sorry, but worse It's not very well, and that in a mouse which is not exactly cheap ......
