I'm surprised that a mouse of this class and sharpened for games will have a double click problem in just half a year! Not for gaming use! I paid the full 8790 for it, I wanted a good mouse for a long time, but it lasted less than any penny mouse. Now I would not buy this mouse even for a third of the price. With its pros: Good coverage. For 11 months, the mouse looks almost like new. The soft is pleasant, glows, flickers. Has cons: After half a year of use, a double click on the scroll appeared, the warranty period is 2 years or a year. At first, it rarely appeared, now with every third press, either a double click or no click. And I used clicking on the scroll only in the browser, that is, there can be no question of any spent resource. Well, it turned out to be uncomfortable in terms of ergonomics, I thought I would get used to it, but no. My hand is medium sized and small for a palm grip. But the question of ergonomics, of course, is subjective. The rubberized sides make your fingers sweat, although peeling them off and cleaning the rubber is inconvenient. A hard cable, although it does not interfere much, but this is definitely not a plus. The scrolling itself is uncomfortable - tight, although maybe it's me, after MXs from Logitech, that I'm already so picky.
