I chose the periphery in the set, and at that time the price was good. I bought Klava Apex m750, also from SS and Rival650 (so that the backlight and effects are synchronized and all that), well, it turned out to me in 12 Keyboard for 8 and mouse for 4, this is the extreme price for this mouse, well, not 10,000 Got pros: SS application, beautiful - fully customizable backlight. Different cons: The side rubber bands immediately peeled off, the backlit charge does not hold (an hour and a half), double click or non-click after six months. PRICE!
