Sam, our unexpected Betta fish birthday gift for our 7-year-old, quickly became a beloved member of our family. To ensure his happiness and comfort in his new home, we had to learn the ropes of Betta care. It was surprising to discover that these little fish, often sold in deli containers at pet stores, require a considerable amount of care. During our research, we learned that Betta fish thrive in water temperatures between 78 to 82 degrees Fahrenheit, and achieving this meant we needed 5 watts of heating power per gallon. That's why we found the 20-watt heater to be a perfect match for our 4-gallon tank.This compact heater was an ideal solution for our uniquely shaped round tank, where our only option was a fully submersible heater. Many other models we came across were bulky and had no suitable attachment points. However, this heater's strong suction cup allowed us to discreetly position it near the rim of the tank, preserving the tank's aesthetics. Not only has it maintained a consistent water temperature of a perfect 80 degrees, but it's also safe to touch, as Sam often swims close to it without harm.One feature we appreciate is the easily visible digital display, which helps us monitor the temperature and ensure Sam's safety. However, my one concern is the auto-shutoff setting, which is set at a rather high 97 degrees. Knowing that Bettas cannot survive in water temperatures exceeding 86 degrees, I can't help but worry about the possibility of returning home to an overheated tank.

Perfect for small tanks or jars, I use it for my 1gal tank with fresh fry and it works perfectly, easy to set temperature, truly convinient to use. Wish the cord would be longer.

**Updated Review** This seller immediately responded to my review and sent me a replacement. My replacement heater works great and I am very happy with it! My original heater plugged into a USB port, the new one has a normal two-prong plug. I'm not sure if that's what made the difference but the new one works really well. Thank you seller!!So sad that this product does not work. I bought it for my 1 gallon, small fish bowl to keep my beta warm as we live in cold climate. I have had it set to 79F for 24 hours and so far it hasn’t gotten warmer than 74F. Additionally, I used a thermometer to test the water temp and it read 4 degrees colder than the display was reading on this thing. Very frustrating. Save your money.

Listen to the other negative reviews. This thing shows the temp changing but in reality it isn’t. This can be verified using another thermometer. This is literally a scam. Returning it.

Works well for my little 2.5 gallon nano tank that I use for a beta and plant. And that it is digitally adjustable makes it even better. Also comes with a suction cup clip to attach inside your tank. Don't expect major temp changes but it will adjust up a few degrees in 5 gallon or smaller tanks. The heating glass is exposed so be sure your fish/snails/shrimp/critters can easily get away from it's glass if it kicks on when they are attached to it.Nice little heater that's easy to setup and use with big temp numbers you can see from across a room. For very small tanks only.

Si me gustó y por eso no lo devolvÃ. Muy preciso, se puede usar para un nanoacuario. Es muy pequeño. Los que ponen mala nota es por que no saben usarlo. Lo recomiendo

No duró más de dos dÃas cuando explotó dentro del nanoacuario, al parecer el cristal no es de buena calidad o venÃa defectuoso
