So I bought this and used it for about 3 months. I moved it to my new tank and it started giving me a fault that there was to great of temperature difference between the two probes. It still works but switches on and off constantly. It will keep temperature but isn’t working properly. When I moved it no cords got pulled on and I can’t see anything physically wrong with it. Inkbird sent me a new one and didn’t want the old one back. If anyone wants it for free to maybe fix or mess around with let me know. If not I’m just going to toss it in the trash.
