Review on Logitech G G603 Lightspeed Wireless Gaming Mouse, Black by Wiktor Michalski (Li ᠌

Solving the problem with the wheel on the G603 (scroll glitches). In general, it turned out to solve the problem very simply and unexpectedly for myself. Just open a large Word file (to control the process) and start scrolling down the pages with sharp but light movements, not paying attention to glitches, as you wind up to the end, start scrolling up. Try not to hit the wheel when scrolling. Continue like this for 3-5 minutes and check if there are less glitches. Twist until the glitches completely stop. It worked for me, and this is without any disassembly and lubrication)) Most likely, when scrolling sharply, due to strong friction, the contacts of the wheel and the encoder rub against each other and clean themselves. In general, completely by accident, but this technique worked. Now everything works without glitches with any scrolling. Hope it helps you too)
