I bought this for my baby's nursery to keep abreast of the humidity level in her room so I know when I need to turn on the humidifier. It works great- it also tells the inside and outdoor temps which are useful, and has a clock.
The only reason I gave it 4 stars is b/c the sensor to measure the outside temp lost it's stick quickly, so it won't stick to the window anymore like it is supposed to- now i just shove it in this little catch on the window screen and it works fine. Th cord also doesn't allow you to shut the window completely, so if you want to lock it, you're out of luck (that is, if you want to measure the outside temp- you don't need to use this feature if you only want to measure the inside temp and humidity).
