I have been typing on my 87UB 55g for 3 months on a daily basis now, it's my main driver.
But today I've noticed that my enter key is REALLY light (feels like 25-30g) compared to all the other keys. It also feels lighter than the shift key below it and the backspace above it.
When I gently tap it (without pressing it, just touching it slightly), it sounds like there is rice paper under it or a slight rattle.
Anybody know what's up? Is it something to worry about or is my OCD playing up again?
