Review on 500W LANZZ Submersible Aquarium Heater with Auto Thermostat, Protective Sleeve, and 3 Suckers - Optimize your Fish Tank Heating System by Danielle Simon

I have a 100 gallon turtle tank that is only about 1/2-3/4 full at any given time and I wanted to replace two heaters, a smaller one is larger . and from February 9, 2019 it is now April 24, 2019 and it has already stopped working. I'm trying to contact Revain to see what we can do to replace it as the product is no longer available for exchange. Very dissatisfied with the lifespan of this heater. I think we need to find a new one.
