Hello everyone, I have an ego twist 650mah. It has worked well for a few months now, but last night the button just dropped out while I was taking a toot. It wasnt dropped, banged or anything, it just broke. The button stayed engaged so I had to give it a slap into my hand to free it. Ever since it has been sunk below the collar surface, however it still works. It doesnt give a click feel anylonger, its just mushy but lights up and fires the battery. I decided to take it apart hoping I would find the obvious problem/ broken piece, but everything still looked ok. My only guess is that the semi-circle U shaped brace that the board rests in may have broken loose. There isnt much room to add a filler, and still get the collar pressed in, so I wasnt sure what to do. Has anyone else experienced this, and if so, how did you fix it?
