Customers say
Customers find the aquarium heater perfect for small tanks, easy to use, and consider it decent value for money. They appreciate its accuracy, with one customer noting it’s spot-on with each other, and like that it shows the current temperature. The temperature control receives mixed feedback – while some say the cube doesn’t overheat, others report it doesn’t reach the desired temperature. The functionality also gets mixed reviews, with some saying it works well for 9-gallon tanks while others report it stops working after two months of use.

Aquarium water heater
I Like how this is small for my 5gallon fish tank , l also like how I can program what temperature I want the water heat up then it automatically shuts of.I can also see the temperature on the power cord that’s a plus . Delivery was very fast & accurate. I would recommend buy this heater for your tank depending on the size.

Suitable for small aquariums
I bought this for my 5 gallon tank and it heats up a little slow, still works fine in a 2.5 gallon tank.

Not to be trusted to do what it is supposed to do
It worked great! Until it didn’t work at all. And that only took a couple of days after I started using it. It now turns on but doesn’t actually heat up. I woke up to my fish tank at 63F, so that was fun.

Good heater for my 2gal
Need to preface with the fact that I have bought both the 10- and 20-watt version of these.I have a 2gal reef tank and the 20watt is a perfect little heater.The 10 watt I use to pre-heat water for water changes. At 2 gallons a water change that is not pre heated is quite the shock on the tank inhabitants.All in all, they are nice little heaters with a display that shows both the set temperature as well as the current water temperature.I will add, that at times the reading can be off by a degree or two. I think this is due to the fact that the heating element and temp sensor are in the same housing, so the reading might be taken at the same time it is heating, or at a time when it is not heating. This is a guess at best.I’ve compared it to two other reading from various thermometers (Stick on, and in tank) All three were one to two degrees off. So who knows.

mini aquarium heater
I have a 1.5 gallon fish thank. I noticed the water was colder than I wanted to be so I bought this mini heater. The heater shuts off when the water is warm enough. The heater does not over heat the water and it is easy to set. I love this heater.

Not Sucky
The suction cup is not very sucky and pulls off of the tank quite often.

Hice una prueba de este mini calentador antes de ponerlo con mis tortugas para ver si funcionaba o si las podÃa quemar, pero nada de eso!!!, Es muy fácil de usar y si calienta el agua, tarda un poco , pero si la calienta, meti mi dedo en el agua que estaba con el calentador y despues en donde tengo a mis tortugas sin uno, y si hay mucha diferencia, te recomiedo comprarlo, vale mucho la pena
