25W 50W 100W 200W 300W Aquarium Heater, Submersible Glass Heater for 10L-300Litres Fish and Turtle Tank (100W for 40-100L)

great product for that price it was over a year ago and still works great. Good quality love it

top quality product. great 300 watt heater and the size is just perfect. always follow the safety guidelines

The heater is working well the only thing that is slightly annoying is the click that you can hear when the heater clicks on.

Perfect. Does exactly what it says.

Seems to work fine a replacement for my old one. This has a nice design and very reasonably priced

Works well. Keeps my turtles happy in the winter months as the water can drop a bit cool. The thermostat is a bit hit and miss but I just keeps tweaking it until it settled at the temperature I needed. It was saying 25 degrees but closer to 23. Just start on the lower side and slowly increase.

The temperature selection is inaccurate, The thermometer which comes with it doesn't actually work!

This is a nice little heater but the temperature gauge seems to be off, when i used this for the first time i had a digital thermometer in my grow out tank, I set the heater to the temp i required and kept a eye on the gauge it started going past with no intentions of stopping so i had to keep bringing it down until i got it to where i needed it to be. when i got it to the right temp i have no longer needed to play with it and it keeps the temperture within range
