My Logitech G203 is still alive after 8 years of constant use. Never tried to fix, but it autorepaired itself of double click (both buttons) , miss click and bad contact. At this point I am afraid of opening it to clean inside and it just cease to exist, I still clean outside tho.
I had one that was my childhood friend and daughter of my mother’s best friend. We threw hints to each other and even lived together for a while due to financial constraints. I am glad she went to another as her mother ended up trying to kill my mother in a road rage. Nothing serious happened to my mother, but I was furious nonetheless and we parted ways. It’s been a decade since I heard anything of her or her mother.
