The perfect heater.
The fish tank heater is easy to install and it heats the tank to the temperature needed. The price was very affordable.. My turtles are enjoying the heat.

Great heater for small tank.
I bought this heater for my daughters new betta fish 2 gallon tank. I love the fact that it suctioned on the side of the tank & also has an auto shut off when it reaches correct temp. He dif. seems to like it being warm.
