Product review (4 stars): They get the job done
They seem to be working well. The view screen is a bit busy, and I wish the temperature was displayed a bit more prominently. But I've gotten used to where to find that information. I'd buy them again, although I might look for thermometers that included humidity next time, instead of this type of set up. If your main goal is to quickly see the humidity in the room, this is definitely the one to go for.
