well i have a stealth which are "shatter proof" which they are VERY sturdy but did not have anough money and got a cheap ass glass heater and this is where it landed me... so now ill stick to nice heaters but they are all doin good and the heat was REALLY high like in the 90s and now around 80 which house is at 78 and my room is very warm due to reptile lights thank god. but from 90s to 78 is a sufficient drop so im glad there acting like there piggy self.
