The heater is easy to use. It's attached to the glass and hasn't moved yet. We didn't have to reattach it. The instructions were easy to follow and easy to use. There is a power switch on the cable. The cable is nice and long. It comes with a temperature sensor that sticks to the outside of the glass. The water temperature was stable. Mushy bits of food bump up in hard-to-reach places. Cleaning is a bit difficult due to the design. There are many small hard-to-reach spots.
