You must be really rough with them svyr. (joking joking)
That's terrible mate, I'm sorry to hear that, hopefully you can get a replacement quickly.
I actually was going to run a thin layer of clear nail polish around mine and seal them further as I also believe in a matter of time that glue will come apart. It's an accident waiting to happen every time you remove the housing, I try to make sure (if I remember) to hold them past that point.
I still use H-300 often,...
