Victoria Fraser –
This controller works perfectly in my 100-gallon marine tank. I can set both heating and cooling at the same time, which is very useful during temperature fluctuations. The display is clear and the sensor stays waterproof even after several weeks of use.
Stephen Rutherford –
Easy to set up and doesn’t require any wiring. I use it to maintain stable temperatures in my reef tank. The dual mode is helpful when the room temperature drops or rises suddenly.

I’ve had this for three months now and it’s been very reliable. The temperature readings are accurate and the alarms help me catch sudden changes early. Great value for the features.
