Query: Cheap, not sure how accurate though.

For the cost it is the best deal I think I have found.Not sure how accurate it is though. I have a more expensive humidity meter and they are about 5-7% different when placed beside each other.Not sure which one is incorrect.I use this one during the winter and keep the room it is in at 50% humidity level with my humidifier.This is a great thing to have when the heat is on during the winter.Sinus problems, respiratory issues, and dry skin are just a few of the things that happen in dry environments.The printed meter on the unit explains what is a good level of humidity is for different situations.
