I like that the monitor shows the current temp as well as desired temp. The temperature gage hangs on the wall for easy access. The suction cups work great and keep it in place.

This is about as easy as it gets. Easy to install and easy to use. More expensive than some other heaters i’ve priced and tried.

I let the water level get a little low (my fault), so part of the heater was exposed.

It keeps my tank between 76-82 degrees.

It only heats, and heats, then heats some more. It works by just heating the water in the tank while the heat also escapes into the surrounding air. The water was overheated.

Caveat emptor. I wish i'd spent a little more, & gotten one that would work for a longer period of time. Don't usually even write reviews.
