Review on 🌡️ The Ultimate Aqueon Submersible Heater: Efficiently Regulate Water Temperature by Stephanie Armijo

I bought this heater last winter and won't use it until next winter. I live in South Florida and only need heating a few months a year. Too bad I didn't check it out right away and now it's too late to go back. I have always bought Aquatop heaters in the past and they are not perfect either. I assume that all heaters die sooner or later. But this heater, after being plugged in for 1 week, started banging very loudly about every 30 seconds. This has never happened with my aquatops, even when there was condensation inside. I just read that knocking can be caused by a bad gasket letting water through and then suddenly evaporating it. Sounds unsafe and I'll throw it away and replace it with my old brand.
