Rated 4 out of 5 by kittenmittensAZ Works well in my 5 gallon
I have a Top Fin 5 gallon glass aquarium and this heater works pretty well in it. It has kept it between 75 and 80 degrees, which is good for my little betta fish. I may opt for a more powerful heater come winter time but for right now and possibly summer time, I think it will work just fine.

I went with this since I do like Aqueons products but this little heater didn't work and stopped working. It only kept my 5 gallon tank at 74 degrees and eventually stopped working. So better to get a normal heater for your tank.

Rated 5 out of 5 by RickyBates Best heater i've owned.
I have a betta in a 5 gallon tank . This wonderful heater keeps my tank 80-82 degrees which is beyond perfect for my betta . He is very active and happy with this heater in his tank . I've had absolutely no problems at all with this heater . It takes about 1-2 hours to heat up but after that it keeps you're tank heated until you unplug it. Some reviews say that the heater over heats or doesn't get hot enough but my heater is staying at the perfect temperature . I would recommend this heater to anyone with a tank 2.5 gallons and up. Also if you buy this tank make sure to buy a thermometer. Overall i'm so happy with this product.

Rated 1 out of 5 by JaHa DO NOT BUY
I just got my betta and I wanted to buy a heater for him. So I bought this heater and a thermometer and set everything up. After 2 hours, I checked the thermometer to make sure that it was working. It was definitely working... so well that it heated the water up to 86 degrees!
I got a sample of the water and measured it using another thermometer. Same result. I unplugged it and returned it the next day.
