Hi, i've had a BFG 150mw laser for about a year and a half and it works great.... it's just the button has seemed to have worn out. Ever since I got it the button has been crappy and has gotten harder and harder to push but now it has completely broken. It also sinks in a little bit ( I think the circut board inside has been bent a bit) It's been broken for about eight months now though, I just finally want to fix it. The thing is though, I have no idea how to get this thing open. I got the bulky head part off but I am stuck on trying to remove the aluminum thermal unit that contains the core. I have put quite alot of pressure on it but it still won't budge. anyone ever open one of these?
