I have the stealth and my only complaint so far is that I can't really tell if it on or not. They gotta put an indicator light on that thing. Ebo jagers, I've had them for years and no complaint from me.
stealth is good if its gonna take bumps.
@ 78 degrees:
Stealth - dead 7 months
Jager - cooked FOWLR tank 1.5 years - also a friend had 3, all 3 cooked tanks at different times over the course of 1 year of use, he used them for breeding discus
Visitherm - from my experience die after 3 years, no issues until then (had on every tank until they died, then switched looking for longevity)
Rena Digital Ti - currently at 5 months, no issues, temp only varies .5 degree - best that i've used yet on Reef system

do you have a GFCI outlet or a Surge Protection outlet? seems its due to spikes if their are spikes and lightnings it will easily burn your equipment if you don't have the proper protection needed. but if it has... sorry to hear that seems pure bad luck on the equipments.
