Thermometers And Humidity Gauges Combination Pack

I have these in my son's hermit crab cage. He's six and for him they are easy to read. he knows where the heat and humidity levels have to be to keep his hermit crabs happy, and he checks his gauges daily. These are relatively cheap, easy to read, and come in very handy for a young pet owner.

My only complaint is that the humidity does sometimes get inside the gauges and makes water-droplets on the inside of the plastic, which makes it harder to read.

Pros: Easy to read, don't take up a lot of space, relatively cheap

Cons: can collect condensation, not very pretty to look at

They work pretty well so I always know what's going on inside the crabitat. However, it really doesn't stick to the side like it's supposed to...kind of irritating. The crabs like to carry them around when they fall off the side if I don't see it right away. Funny crabs!

Pros: Keeps you informed

Cons: Won't stick
