Good heater
Pros: Accurate, effective
I use the 300w version and was afraid I would need a second to heat my 75 gallon tank, but it works fine on its own. Seems accurate with little temp fluctuation.

EHEIM TRU TEMP
Pros: Easily calibrated, Price for the quality is unbeatable.
Cons: none
One of the most reliable heater out in the market. The only way this breaks is with a hammer. Very reliable!

Never failed Me
Pros: Reliable, tuneable, tough, safe
Cons: Glass, but they are tough, haven’t broken one yet.
I finally replaced both of My 6 year old jaeger heaters out of paranoia. They were both working when I took them out. Installed 2 new ones. Won’t even shop around for other ones. UL listed, 3 year warranty. An old Gold standard for heaters, imo.

Didn't last very long
Pros: Steady temperature
Cons: Crapped out pretty quickly
My 150W heater burned up this week. It lasted in my saltwater tank about 21 months. At least it held a steady temperature and didn't do anything bad to my tank when it failed. Going to try something different this time.
