Unfortunately thats not a uncommon experience with Hyrdrofarm. [Begin personal story] On a personal note I got one to take a look at. The pcb was a mess. I touched up solder points before i even plugged it in. I messed with it for a bit to test it out. I wasn't impressed. My father needed a thermostat to run a small 600 watt room heater. I figured it would be a good chance to put some miles on it and see how it held up. Two weeks later it no longer was outputting heat and if I remember right was also resetting itself. In the garbage it went. [end personal story]
