## Customer Reviews

### ⭐⭐⭐⭐⭐ Great value for this heater.Works great .Will buy again.
*by L***. on February 27, 2020*

After a heater fail had to order one and get it here fast. I set the heater and put it in the tank.Waited 15 min.then plugged it in. The next morning the water temp was right on the money.My fish thank you.

### ⭐⭐⭐⭐ Good heater!
*by H***Y on February 10, 2020*

Great heater! My only complaint is that it is about 3-5 degrees hotter than it should be. I originally had it set at 77 and it was heating just right at 80. I cut it back to 75 and it is heating right at 79. My betta fish love it.

### ⭐⭐⭐ So far, not accurate.
*by R***Y on July 18, 2019*

I've only had this heater in the tank for 24 hours. I followed the instructions and didn't plug it in for at least 30 minutes. I set it halfway between 75 and 80 degrees. When I checked it this morning the water was at 83. I've turned it down to 75 but the light is still on. Waiting for a few days to decide on returning it. After a few days, I found that this item would not properly maintain temperature so it has been returned.
