HydorTHEO 100 W Aquarium Turtle Tank Heater, Submersible, Anti-Thermal Shock, Shatterproof, with Graduated Scale and Suction Cups, Black

I haven't had it very long but so far so good. It's smaller than what I thought which I'm happy about as I don't like big filters and heaters taking up my aquarium space. My last one was small but this is even smaller. The only thing I could pick on atm is that in the picture the switch bit on top looks pink, which I liked the idea of, but it's more of a dark red

Great little heater, can't fault the accuracy. Easy to adjust dial, unlike some cheaper heaters that pull off the suction cups.

Purchased this item after reading the reviews and was impressed with people comments how accurate this heater wasI have found this not to be the case to get a tank temperature of 25c the heater is set at 23c which would be ok but the temperature is not stable and various between 25c and 27c which defeates the point of buying in the first place

Really good heater, accurate and does the job

Do his job good for the moment

Have used this brand before and is very good quality and reliable.Good packaging and fast delivery but as expected fora prime member

Excellent worth paying the extra for good temperature control just be careful when buying as not to over spec the heater to the tank or the heater will over shoot the temperature set point

Got to hot the heater even on a low temperature killed all my fish
