Review on Aquarium Submersible Temperature Intelligent Controller by Cynthia Cooper

After reading too many horrible reviews about cooking and killing fish with almost any aquarium heater on Amazon, I took a chance and decided on this one after looking at many heaters. The second week, and this is very accurate, seems very safe for our little Betta in his 3.5 gallon plastic tank. It has great features like auto shut off and save last set temperature in case of power failure etc. Highly recommend! Also, feel safe knowing it's unbreakable! Read some nightmarish reviews about exploding others etc.
