How much was that digital Therm/Hydro?

I would return it and get either of the following. Even though it is opened return it and tell them there are no instructions and it sucks lol.

Amazon.com: Zoo Med HygroTherm Humidity and Temperature Controller: Pet Supplies

Amazon.com: Exo Terra Digital Combination Thermometer/Hygrometer: Pet Supplies

They are both super simple to setup and the one that isn't the Zoo Med Hydro Therm is super affordable.
