Seems to hold the temp well. Comes with a stick on thermometer. Review: Can’t heat up tank *FIXED* - Update: 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. ## Features - 🐟HITOP aquarium heater 50W, length 7 inch, power cord 4.9ft, designed for small fish tanks, recommended for aquariums 8-16 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.

Have no problems. I truly think it is the best heater we have gotten. You can maintain the temp in the tank very easily. **Q: How can I get replacement suction cups?** A: Search Amazon **Q: Is that ok get 200w heater for 10 gallon tank?** A: The 200W heater is too powerful for a 10 gallon fish tank, choosing 50W or 100W will be better. **Q: Do these have some kind of warranty? I got mine in September and it broke today. Just cracked and stopped heating.** A: I do not believe they have any warranty. I’ve had no problems with mine. It’s extremely odd for them to crack unless possibly it cracked from shock or maybe you were changing the water and forgot to unplug it because if the glass gets heated while the elements heating up and then you add water it could crack it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well *by S***T on April 14, 2026* The heater works fine, I use it in a 5 gallon tank.
