Review title: This heater is just waiting for you to screw up.
Product review: I had this heater for maybe 3 days when it shorted out. I read the instructions and did not plug it in until it was submerged. I read reviews stating how you had to have it in a liquid or it would short out. Maybe someone should have said it needed to be COMPLETELY submerged, almost all the way to the handle. In my opinion it's not worth a penny.
