I expected that the cable would be oak, but unpacked it, leveled it with my fingers and ok. I don't notice it at all. glides moderately easily and oily (optimal) the mouse is moderately light, there are no problems tearing it off the carpet. the tenacity of the side cover is at "4", but the light weight helps. after a heavier mouse did not notice discomfort, the mouse is quite felt in the hand. not air. button under the wheel judging by the sound of a square membrane. the wheel has pretty clear cut-offs. without noticeable backlash, not ideal but not quite Ge. there are no special claims to the side. I don't need lighting. Made static at minimum brightness. as a result, of the minuses, only the sound of scrolling away from you, a slightly resonant sound of the wheel button. and a rather high separation height (although those who did not use more expensive sensors would not have noticed the difference) as a result, the question of price, since there are a lot of competitors with the same quality.
