Damn, hadn't heard about any separating :| I've been looking for work all summer so I have only been paintballing once, and had got to use my thermal once late last year... my mom moved my stuff over the winter, however, and masks ended up on the bottom of the gear "pile" -__-
So, when I went to rinse off my masks, the Profiler and it's used-once lens got half full of water! I let them dry out, but I haven't field tested to see if they fog (because I'd have to order online to get new ones)...
I better grab one or two soon! :|
