Review: Works well - I have two of these in a 75gallon tank two different ones that is. Keeps temps where they need to be and no issues.
Review: Nice Heater - So far so good. I like the digital display so I can see the status of it at a quick glance. It seems a little large for my tank, but that's ok. It is very easy to install and set up. The controls are mid-line on the power cord, so you can set the temp or change it with out removing the heater or getting your hands wet. It does a great job of maintaining the temp to within a degree of what is set.

*by S***Z on July 22, 2025*

First dont buy this product! I figured i would give them multiple chances and this thing could have easily burned my house down tonight! This product failed in such a way that it blew my breaker in my house before it could cause such chaos elsewhere killing my fish i have given them multiple chances on different watts of heaters of this model and even other products of theirs i will not do business with their products and i recommend you dont either im lucky i found the problem quickly and my electricity did its job and saved me from a big problem.
