I spent almost $30 each for three of these and they didn’t even come with batteries. Couldn’t tell you how they work. If I’m spending this much on something I would have hoped they would have at least had batteries.

Returning. Maybe I just happened to get a defective thermostat, but my house is no 106 right now. It seemed to work at first but I felt like the readings might be off, and then it started giving readings that were just crazy.

Love this device.

I have two of them. 1 for the cool side and one for the hot side of a 20L reptile tank and they work great. They are helpful tool for maintaining optimal humidity

I have two of them. 1 for the cool side and one for the hot side of a 20L reptile tank and they work great. They are helpful tool for maintaining optimal humidity and temp. Could not imaging having a proper setup without them. My only complaint is that I wish the LCD screen was backlit or had a light button on it so it made reading them easier. As it stand I have to use a small flashlight to read them. For that, 4 stars. They could a 5 with a lit screen.
