Review on 🐠 SZELAM Submersible Aquarium Heater 100W 300W 500W - Fish Tank Heater with Dual Temperature Displays and External Intelligent LED Digital Temperature Controller - 2 Suction Cups - Ideal for 26-132 Gallon Tanks by Megan Sweet

Revainrating 1 out of 5

Terrible product. Completely unreliable.

This heater is 55 gallons. Aquarium. Temperature control was everywhere: every two minutes from 85 to 70 degrees and back. There were no fish in the tank so I left the heater on overnight hoping it would settle to the temperature I had set. It's not like this. It just kept breaking. If you are looking for a reliable heater, you should look elsewhere.

Pros
  • Beautiful packaging
Cons
  • Unbelievable price
