Review on Gamepad Gamesir G4 Pro, black by Wiktor wikliski ᠌

I am writing a review after 3 months of use, at first everything was fine, but after 2 and a half months of use, both sticks had dead zones, and at the same time, I don’t know what’s the matter, I didn’t drop it, I didn’t take it with greasy hands, I kept the gamepad clean. In general, the gamepad is normal, but the sticks are very upset even for three months they did not work so that they would not be defective. I tried to reset the gamepad settings via reset did not help.
