Product review (4 stars): Upgrade From 1 Star to 4
High current usage, thus short battery life, one month battery life promotes battery leakage in different battery brands, and generally just too much attention for what it is. Can't recommend!

Just out of curiosity, I contacted Acurite and purchased a replacement outdoor sensor. It has been in use now for about 6 months, and I 've checked on the battery a couple times, but found it unnecessary to replace, yet. I'm upgrading my rating from one to four.
