Review on Submersible Fish Tank Heater - 500W Digital Aquarium Heater with Readout for 60-100-150 Gallon Saltwater or Freshwater, External Thermostat Titanium Safe Controller, Includes 2 Artificial Plants as a Gift by Summer Lopez

I ordered this heater for my 60 gallon after a couple of failed tries with a cheaper heater that didn't even come close to being advertised. Tank on Solid Rock 86 (needs higher temp to combat their infestation). I mean it hasn't changed more than a tenth of a degree since the desired temperature was reached. ** Tank temperature is displayed directly on the heater in numbers large enough to be read from anywhere in the room. Very convenient. **You can set your desired heating temperature on the power cord, avoiding the pain in the ass of having to put your hand in the tank and do it like that. ** It looks cool! long gone. So yes, highly recommended! Good product.
