### ⭐ Review
*by S***D on 23 November 2024*

At first this heater was amazing and did everything I wanted it to do but today when I when to check on my fish. I realized their morning light bar did not turn on so I checked my power brick if it was on but the switch was turned on but I could not see any light. So, I checked their tank and the heater broke into pieces so I had to quickly turn off my breaker to minimize any risk when taking the fish out. Anyway, I would not recommend this product as this is a safety hazard to humans and fish. As I had an expensive discus pair in the tank which they got a bruised but now in a recovery tank. Would like a refund or some sort of compensation. Have a good day everyone, hope other people do not have the same experience as I had.
