This will keep your water at a constant temp. Unfortunately, that temp is about 85 degrees Fahrenheit. Way too hot for my needs. One of my fish wedged itself behind it and was cooked. Yes, it was absolutely fully submerged.

Very easy to use. Good quality. I really like this heater and the thermometer that comes with it is excellent. Would have given 5 stars but the neat thermometer broke in less than a month. Can't find just the digital thermometer.

Keeps our betta 5 gallon tank at around 82 Fahrenheit. It’s compact in size and suction cup holds it in place. Happy with product

Deben ser los calentadores más estéticos del mercado, desafortunadamente no cumple con su función.Tengo un tortugario de 6 litros y solo eleva la temperatura un par de grados. Menos de lo que promete.

Absolutely love and so does my Beta. It does keep the temoerature between 77° to 86° as advertised. My Beta is always next to it and loves the heat. Whenever it is heating the tank up the little red light turns on. No issues at all even for my 3 gallon tank.

Loved the shape and size, but in two weeks it stopped working. Good thing I waited to add a fish. The temp dropped really low before I notice because the thermostat was wrong. Noticed it when I did a partial water change and the water was really cold. Too bad because it’s a nice slim design. I also notice no contact number.

This gets the job done i give 4 out of 5 stars. While you can't control the exact temperature, this does in fact keep your tank at the temperatures specified. It will very throughout the day but will always be within the specified range. It does suction cup to the wall decently and I personally have not had an issue with the suction power of the heater itself. The digital thermometer didn't want to suction at first and would float away but after a few tries I got it to sit in place. (Away from any current in the tank) all in all a decent buy.
