Great little heater for my 5gal shrimp tank!
Very well built product and heats up quickly.
This heater is doing a great job so far. It’s in used in 220 gallon tank. The water temperature start point was 71F. The temperature was set for 80F. A few stand out feature. 1. The digital features is easy to use and set up. 2. The water quickly reached set temperature within an hour. 3. The digital display clearly shows temperature and wattage being used. 4. It came with two accessories to easily mount the digital control. Two suction cup to hold the heater in place. An extra suction cup was also provided. A minor negative is the size of the heater. It’s larger than I expected. It just a very minor issue. Overall I am impress with the heater.
