Query: Was curious how long batteries would last

I bought this at a local store for about 10 bucks a little over a week ago. Was Googling on this unit to find out about battery life and there was a linky to Amazon. I noticed the battery comments and thought to myself well the outside unit has been running on the same batteries for 10 days. So maybe it was just a bunch of older units with battery issues. An hour later I looked for the temperature outside and the outside units batteries are dead. I almost fell on the floor from laughter. If, for no other reason, you have to love Amazon for allowing truthful comments on products.These comments are right on.
