hygger First Impressions

This heater works great.

The red light means it's off, blue light means the temperature is constant. It does blend well in some setups and may look bulky in others. I have had to turn the dial to about 78-79 for the tank to stay around 76 degrees. This does a great job at regulating the temp in my 10 gallon. This heater works, but the dial it isn't very accurate. My heater is fully submerged underwater and works perfectly fine. The bonus digital thermometer it came with has been super helpful, and is accurate.

hygger Final Thoughts

I have a 5.

I appreciate the exterior temp readout and control module. I will definitely be buying another one for my other tanks at bigger one. I adjusted the set temperature a little lower to be more in the range I wanted. What more could you ask for great job Hygger Duncan. The heater is being used in a 40 gallon breeder. When i installed them, i let them sit in the tanks without power for 6-24 hours. Temperature is slightly off by running a little warmer.

4.2
