## Customer Reviews

### ⭐⭐⭐⭐⭐ Discrete reliable heater for small tanks
*by S***P on June 29, 2025*

These heaters are great for small aquariums. I have two 5.5g aquariums and these heaters work like a charm. Easy to adjust the temperature rather than playing a guessing game.

### ⭐⭐⭐⭐⭐ Control and Value
*by A***Y on June 14, 2025*

Works extremely well for what it is. I'm using for 5.5 gallon aquarium. Love that it has an automatic shut off/no heating feature if the temp goes one tick above the set temp. May end up buying again for another tank. I enjoy the heaters that you can control the setting on. The preset heaters that have no control option are all trash. Value is nice too.

### ⭐⭐⭐⭐⭐ Awesome service
*by G***N on March 19, 2024*

I have had the heater since August (it’s now March) and the other day the blue light stopped working and the heater started going up in temp, I emailed Hygger and the immediately sent a new heater the service was amazing. Just to note I did have a backup heater which I have for both of my tanks. I have many Hygger products and love them and now I love them even more. you can’t beat good service :)
