09-08-2025The heater works absolutely great!! I was scared of buying it online, but it was a great decision, you can adjust whatever temperature you want and the instructions come clear. It took about 4 hours to heat up completely and start the cycle, you can see the red light dot when it's doing it's thing and it has kept the temperature perfect for my future betta! I'm glad I chose this one

09-08-2025This heater has been working great for three months, we have it hooked to a soil thermometer that lets us set the max point, to control the water temp and it stays within 2° of our set point all the time. We have it in a 10 gallon tank and keep it at 79°.

09-08-2025Update: the HITOP team reached out to me immediately after writing this review, and offered a full refund for the broken product. They then reached out again to offer a brand new heater to replace the broken one. The team has been wonderful to work with, and they go the extra mile to help customers feel satisfied. I’m sure I got a faulty heater in the original package, as it was no fault of HITOP, but I so appreciate they made things right. The new heater works phenomenal.Original: After 9 years my original tank heater for my 10 gallon kicked the bucket. As I was going to redo my tank anyways, I ordered this heater but used two 5 gallon rated heaters for the mean time. Those two were able to keep the tank at a consistent 78° while the room is usually 68-69. Unfortunately I think I got a faulty heater as the light turns red but the heater itself is never warm, and my tank is getting colder.
🐟HITOP aquarium heater 50W, length 7.2-inch, power cord 4.9ft, designed for small fish tanks, recommended for aquariums up to 15 Gallons. 🐟 Thickened Glass: 2mm thickened quartz glass, 33% thicker than 1.5mm normal aquarium heaters, much safer for human and your lovely fishes, your pets will no longer fear the winter. 🐟Adjustable and easy to use: This aquarium heater, adjustable temperature range 68 ~ 93 °F, after setting the temp you want, will on or shut off automatically when the water temperature changes, no extra adjustment is required. 🐟Accurate Temperature Control: This fish tank heater built-in thermostat, will automatically keep the water at the set temperature within±2°F error. Comes with an sticker thermometer to detect water temp at any time. 🐟 Easier installation, you can install it with any angle by 2 powerful suction cups, just make sure it is under water fully.
