## Customer Reviews

### ⭐⭐⭐⭐⭐ Great for price and quality!!! Love it
*by A***  on July 30, 2025*

The 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

### ⭐⭐⭐⭐⭐ Good heater so far
*by R***Y on July 30, 2025*

This 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°.

### ⭐⭐⭐⭐⭐ Can’t heat up tank *FIXED*
*by L***Y on April 17, 2025*

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.
