Next heater I try will be jebo from Ken or a Hydor inline, I recently had a stealth stick on, first of the many visitherms I've had. My LFS guy said Renas & stealths have been being returned a lot lately
my jager heater is 3 years old and is still running perfect. still looks good too! get a jaeger and then turn it low for your tank. 50 watt size. it'll all be fine after that.
