Reliable Humidity and Temperature Gauge

I used one of these, it has worked great for the past year with no problems.

That my friend looks like a decent idea. The reviews look solid as well, generally easy to calibrate. Just where exactly do you mount yours if i might ask?

For my pacman setup i put the gauge about an inch above the Eco earth. All i use are two magnates one on the outside/inside of the tank to hold in place.
