Query: Good product.

This is a pretty simple and straight-forward Hygrometer / Thermometer. The readings are accurate.The only thing, I wished it had was some kind of button which will switch on a small light within the display. That would have been a great feature to have, since you can see the reading, without having to switch on the light. That's a great thing to have, especially since I am using it in my son's room.
