Review on LANZZ Aquarium Submersible Thermometer Thermostat by Emily Wright

Based on my observations, this thermometer is completely off. It reads a few degrees higher than what the actual temperature is. This is concerning for the wellbeing of my fish. The pros are that it is small and doesn't take up too much space in the tank.However the cons outweigh this benefit. Pet Supplies should not include unreliable products like this one. I do not recommend purchasing this thermometer..
