so look, I compare head to head - logitek 903 is declared 170 hours, in fact it lives more than a month, the size is declared 100 hours and in fact it lives 12 days, namely, 95% of the charge on May 12, 2022, 30% of the charge on May 21, 2022, 12% on May 23 202222, and the same on the 23rd but at night already 5% The second moment, the side rubber bands are not strongly pressed to the body, because of which the sides crackle stupidly, wildly infuriates, you can’t even imagine how, nothing cracks on a mouse for 100, and cracks on a sizer for 9k, it’s normal ! PS Why did I decide to change the mouse from Logitek to Razer? Yes, because Logitek started double-clicking after 2 months! a mouse under 10kr stands for a minute, I don’t know what about expensive mice, they are stupidly disposable ! I don't have high expectations! I just want the mice to work properly! without any defects! if in a couple of months it doesn’t start double-clicking, I will increase the rating from 1 point to 3
