09-08-2025The heater does exactly what it should. It keeps my 5.5 gallon tank right at 78 degrees F. I installed it horizontal about an inch off the substrate in the back of the tank and my betta loves hanging around it. It's a little worrisome, but I figure he knows what's best for him. ?? The thermometer that sticks to the outside of the tank doesn't work at all. I left it for a week and it never displayed a temp. I bought a suction thermometer that goes on the inside of the tank. I put it on one of the sides and it verifies my temp is always 78. Overall, very happy with the purchase.

09-08-2025I’ve been using this in a 5 gallon beta tank for a few months now and I haven’t had any issues! The temperature is pretty consistent and it’s a great heater for what you pay. I’ve had tons of issues with heaters not suctions properly to the sides of tanks but this hasn’t moved at all! The light is a little bright on it but we keep our tank in the living room. I would definitely recommend it!
