Review: Holds temperature perfectly - We use this heater in an above ground tank with 2 koi and snails. In our Montana this is holding our temperature right where we want it. The way we use it makes it hard to see the LED digital display but when we take it out of the water it is easy to read.
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.
