Reliable heaters IME
reviewerbadge
PROS
Temp dial is a little stiff so it doesn't change on accident, nice thick power cord instead of a cheesy one like on other heaters
CONS
Length is sometimes difficult to fit into back of tanks
REVIEW
I have used several of these heaters of varying wattages and have never had any issues with them. They are a little bit big which sometimes makes it difficult to fit them in snug places such as a sumo chamber or AIO tank. Otherwise I really like these and will continue to use them

REVIEW
I'm really happy with this heater. I've got the 150 watt in a 75 gallon tank. My water temp stays within about two degrees of where it's set. It's a tad bit long.
