Yikes, somehow I didn't know this, I've used and am using this type of heater right now. I always thought they were well made, I haven't had any issues yet and been using one for 3yrs. I was always worried about glass ones crapping out/breaking (which I have had happen) which was why I switched to stealth in the 1st place! Apparently the stealth's suck too
Looks like I'll be looking for a new heater.
