1. Perhaps a marriage was caught, but after two months the LMB does not work adequately. Either the click does not work, or, accordingly, it is not pressed if a long clamp is needed. Disassembling the mouse will not work, as I understand it: flat hats. Yes, and I don’t want to deal with the preparation of the device at such a price and such a period of use. The good old palm strike on the button itself helps, but it saves more often not for a very long time, if at all. Moreover, the matter is in the clamping force, as if, because sometimes you clamp it specially harder to "grab", but it only jumps according to the statements "took" - "released" even faster. What to work, what to play when this attack occurs in the LMB is impossible.
2. Backlash and volume of buttons. If you can put up with the volume, then the backlash is incredibly annoying. Zhamkayuschie plastic when depressing the buttons, the finger itself goes along with the buttons. Maybe for an amateur, but still I want the button to be more dense.
3. SCM when scrolling at first was quite dense, pleasant, literally a month later it became more viscous. Also not a plus.
4. Weight. Of course, subjective, but for a gaming mouse, it should have been at least a little heavier. Considering also that the center of gravity is in the back (by and large because of the battery) - well, that's it.
5. It is also worth noting that there is no backlight. No. On the one hand, plus to power consumption, therefore, the battery life is increased. On the other hand, she would be very out of place here. But the most important thing is that in some pictures there is a backlight. What for? Make the picture look better?! So make a mouse then)) It looks great. Although I can imagine how quickly the batteries would fly away - they don’t last very long anyway .
