Not a bad investment.
Love it. Works a great for my 57L fluval flex tank. Looks as if it warms the water without pushing itself to the limit. The control is not very accurate though so watch out for that.

Slender design, reliable and reasonably priced
Good little heater, maintains the water temp no problems in my 50l aquarium. Nice and slender also to fit into my filtration compartment. Also have a fluval E advanced which I prefer (in another aquarium), buy it is bulkier and more expensive, however it has a digital readout and advanced features. But the M50 does all it needs to, has an easy to operate temperature knob, and a slender design more suited to a smaller aquarium or a hidden filter compartment.

Very fast delivery
I have give this a five star more for the fast delivery and that is came in one piece. I did not use it because it was to big for the tank I wanted to use it for and returned it

Nice Heater, until it goes wrong.
Does the job, sadly mine is now stuck and my Betta tank temp has shot up to 84 degrees. Thankfully I have a spare 50w heater.

Toller Heizstab! Kann ganz unter Wasser gesteckt werden. Schaltet ab und an den Sensor ein, um die Temperatur zu überprüfen. Seit einem Monat im Gebrauch und die Temperatur bleibt konstant. Gut verarbeitet.
