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.

Nice Heater
So far so good. I like the digital display so I can see the status of it at a quick glance. It seems a little large for my tank, but that's ok. It is very easy to install and set up. The controls are mid-line on the power cord, so you can set the temp or change it with out removing the heater or getting your hands wet. It does a great job of maintaining the temp to within a degree of what is set.

Easy install/setup & great temperature display.
Bought as backup to the same model I just had to put in as the previous heater crapped out as they always do after a couple years when you least expect it. Very easy to setup and has a highly visible digital temperature display. Highly recommend. Always keep a backup handy if you value the lives of your fish.

Stopped working after removing for summer
Purchased Nov 2023 and safely removed it and packaged up for summer. Now it won’t work for this winter. No way to tell why. This is sad because our turtle needs this and we spent a lot of money on something that only lasted 4-5 months. Dis anyone else experience this? Or how to fix it? It worked really well last winter.
