I bought it for 7.5 k, I used it for about six months, yes, a really comfortable mouse, you understand this only when you pick up another mouse. A friend advised the mouse, warning in advance that there would be enough naga for about two years, after a specified period, the left button of the mouse begins to "click", that is, instead of one click, do several. Ok, I think two years, 7.5 k is basically normal, especially considering that I need a gaming mouse with a bunch of buttons, given the lack of analogues (at the time of purchase there was only one alternative). The mouse worked correctly for half a year. Now it needs to be led to the sc, Guys from the raiser - seriously? after half a year, a gaming mouse for 7.5k stops working normally? I doubt that I will continue to buy any product of your brand.
