The media could not be loaded.Value is fantastic for how small it is. I have a lagoon tank and many heaters don’t fit in, so the design was great as well.Temperature control is great, staying within .2 degrees from what my thermometer says. That being said, it has a LOUD “click” sound when going from heating to off. Once it gets to the correct temp, it is CONSTANTLY turning on and off. In the last minute I’ve heard it click 9 times so far. Easily 5 stars for my 25g lagoon tank if not for this issue.

Rating: 5/5 StarsI’m super impressed with this heater! It stays securely suctioned to the back of the tank and maintains excellent accuracy. The design looks great, though I do wish it were a bit flatter. Overall, very happy with it!
