## Customer Reviews

### ⭐⭐⭐⭐⭐ Fish are Warm Again
*by M***S on September 10, 2025*

I waited a while before writing this review, as I wanted to make sure that it was long lasting and durable. I love the ease of set up, operation, and the constant display of the current temperature. We will see how durable it is this winter. It is such a great price, I will get another one to take some of the strain of this one this winter.Update:This is my third of these. The first was a test. It worked great. So I ordered another since a different brand heater burned out. Then I purchased this one for another tank. All are running now. I expect they will give me years of good service. I like the current temp, set temp, and wattage display. Very good design.

### ⭐⭐⭐⭐⭐ Works very well
*by P***Y on September 15, 2025*

Be careful with the 1000 watt heaters. If you use more than one it will pop breakers, sometimes thermostat is off a dregree or two

### ⭐⭐⭐⭐⭐ Easily hidden
*by S***. on September 22, 2025*
