I was using 2 Stealth Pro Heaters until I found out about the recall I was sent 2 Visitherms they are nothing but junk!!!! the stealth's were in my old Fresh Cichlid tank for over 3 years no issues! if they lasted that long without exploding what's the chance of them failing? the visitherms thermostats are way off one wont turn on unless the water is below 60f and it's turned all the way up the other one drifts + - 10f I can't trust them!!! anyone know if going back to the Stealth's would be to risky since they worked for so long? was it every one or only certain ones that were faulty? anyone know? or can someone suggest a pair that I can rely on that are not made of glass.
