HP-608 Quartz Aquarium Fish Tank Heater Submersible Thermostat 25w to 300w (50w)

It's very good consistent with the thermometer.

Good value after shopping around - works perfectly well - no complaints at all

Good item well priced

Goes really well in my 29L tank and warms it very quickly. Not very accurate with the temperature but as long as you check it with a thermometer you can easily get the right setting

I have found the ones i received have been stable, only fluctuation has been caused by room temperature not the heater. When setting up , a little tweaking is necessary to get to the right temperature, rather than going off the temp markings on the unit, they seem to within tolerence of 1 degree, but once set, i have not touched them since.

Keeps my 50 l tank at a steady temperature. Just don't take it out of the water for too long while switched on,it gets very hot, very quickly, and starts to sizzle!needs the water to keep it at the right temp!x

Cracking little heater! I bought this for my 20ltr tank, and it works as well as it is supposed to, you can clearly see what the temperature should be, and i have confirmation from my thermometer, very stable temperatures! The suction cups also hold this item steady in the water, in fact you need to give them a good tug if you want to move it or remove it, their pretty safe. So glad i bought this heater, it is a bargain and we all love a bargain eh!

Sadly, this is a defective product and is unsafe. it melted the bracket in the water after only three months use.

Molto instabile e segna due gradi in più di quello effettivi
