Since I work on computers a lot, I have found over time that I can work longer if I take with a vertical mouse. That's my 2 mouse in the design and the mouse I'm really very satisfied! The feel is a real Super flatterer, because the mouse is completely rubberized, the blue LED strip enhances the mouse, it's a real eye-catcher.
The mouse itself does not work on all surfaces but but that's not that important to me. Thanks to good mouse pad. All in all is very well made and mouse very comfortable to hold without the usual pain. Good keystroke round off the whole thing.
My full recommendation for the PC everyday unsuitable for gamers!
