Works great!

Heats my 1 1/2 gallon to perfect temp and stays put!

Good heater for price

Small and easy to hide. Keeping my tank a consistant 80°. My sucker fish loves hanging out on it. I wish it has a light to tell you if it's working or not because mine dosent have a light. So I've been very very cautious watching the temp. This is in my 5.5 gallon tank and heating it perfectly fine.

Funciona en 1 galón.

Muy bueno, se apaga cuando llega a la temperatura adecuada.

Tank Heater

Product work wonderfully. Very happy with it. Thank you

Reliable

I’m using this heater in a 3.5g acrylic cherry shrimp setup. It works perfectly and stays put. There is no temperature gauge however it does regulate itself to keep my water temp at 77 which is perfect for my needs.

Does what it’s supposed to.

This has been a wonderful heater so far. No complaints what so ever. It stays where it should water temp wise and suction wise. Our betta is a happier fish with heater. We’ve had no problems with it so far.

It works great

So far so good. Everything's working properly and we have no complaints

Great product, easy to use, no hassle.

Product works perfectly. Keeps the tank between 77 and 79 degrees while our house stays much cooler. It is preset, so no dials to turns or temps to adjust. Perfect for busy people that want something self sufficient. Our 2 Bettas have flourished since getting this product and are making "happy bubbles" on top of the water for the first time ever. Great product!
