Using this for work and various video games (cs). Very light mouse, almost feels like air. Build quality is excellent, the materials are pleasant to the touch. The sensor is very precise and smooth, this mouse wont let you down in a clutch. No issues with battery life (multiple full days), just keep a usb-c cable nearby. My phone charger is multipurpose now, phone/headset/mouse.
The only issue is the middle click (mouse3): when held down, it can register multiple clicks when slightly changing pressure. For gaming, no big deal; for working, very lame (can close/open multiple tabs by accident). From forums/reddit, this is common to most (if not all) superlights.
I've used the superlight for several months now with no new issues (other than the middle button). Before this, I've had at least seven wired and later wireless g703s. Something usually breaks within a year or so (left/right double clicking, mouse wheel issues, etc.). I expect the same for the superlight. That's gaming, cant help it. Might sound bad, but both g703 and superlight are excellent mice. With heavy use, it is inevitable that something breaks eventually. If looking for cheaper mice, g703 is a heavier alternative.
pros: -"super light" -great sensor -no issues with logitech drivers -logitech good customer service (can RMA, I got like 3 free g703 after issues with the purchased ones)
cons: -no dpi shift button -inconsistent middle mouse, can register multiple clicks while holding m3 down (without letting go) -scroll wheel feedback is somewhat weak
