So I got this pink 650 x2 about 4 weeks ago. I was wondering if anyone else had problems with the button on the manual sticking sometimes? It's not every time I use it, but at least half of my pushes I have to kind of grab it with my fingernail and pull it back out. I'm afraid this will burn my coils or hurt the battery somehow if I don't notice it on time. It just started happening yesterday, and I don't recall getting any juice or anything on it
