Product review (4 stars): Good thermometer
I had wanted an indoor outdoor thermometer for a long time.  Then I found this one on Amazon's website and ordered 4 of them.  The other 3 I gave away as gifts.

The one thing I don't like is that you can't see both indoor and outdoor temperatures at the same time.  The accuracy seems good within a deg or so.  Hard to judge the humidity accuracy but seems to be fairly close. Another thing is if you live in extremely cold areas you will need lithium batteries for the ouside wireless unit. So I rated this 4 stars.
