Product review (5 stars): Very handy
We got this just a few weeks ago and so far have been happy with it. We were deciding between this and a La Crosse model which had a more attractive case but thought that this one had features we most wanted (didn't need the time). It tells the temperature and humidity outside and inside at a glance. We have not had an outdoor thermometer that needed batteries before so hope that does not require a lot of maintenance. We are using lithium for the outside unit as others have suggested.
