    I currently use two of these for my two Discus tanks as overheat protection w my Finnex HMX Heaters. They are accurate, easy to set/use and are reliable. The previous brand I used only worked for a couple of months. These have been running for nearly a year. This order is for a backup should one ever fail. I use the controller to shut off my heaters in case of a malfunction. It does not operate as a thermostat......the heaters do that. This unit is vastly superior to the Inkbirds used previously. I highly recommend the fishes lives depend on it.
