I bought a mouse much cheaper than the price of the store for balls. 11000 is definitely not worth it. In general, the mouse is pleasant and, most importantly, functional for me (and you can connect to a Mac via Bluetooth and to a PC via a “whistle”) micro usb is of course a pain. I have a negative attitude towards Razor, since durability is not their forte. Style and other highlights, yes, they are at their best. For 5-6000 an excellent mouse, but I wouldn’t give it for anything else.
