I cannot recommend this mouse to those who primarily buy a device for a comfortable and high-quality game. I’ll note the above inconveniences for 500 rival, why was this one so spoiled by a huge dpi change button and notches for backlighting? What kind of normal player changes DPI often? Everyone I play at 400-800 dpi gets used to one sense and does not change it. Make a DPI switch button at the bottom of the mouse. Now I had to take a mouse from Logitech, I hope that I will change it to stealth series in the future if they release something really for a comfortable game in terms of shape and good results. With 3 buttons for the thumb, it would be better to make them like a 500. And the weight of the mouse would be around 80-95 gr. Yes, and I would make its height a little lower 40 mm somewhere.
