The mouse may appeal to beginners, but definitely not worth the money. It turned out to be worse than my Bloody V8 and an order of magnitude worse than Bloody T7 (both 2 thousand each), the second of which broke down, and the first of which had a delay, which is why I bought a new, more expensive one, but in vain, I have to make a return, this is nowhere good. Bottom line: A mouse for 5 thousand is worse than two mice for 2 thousand.
