Bests & Worsts Reviews from Amazon

Initially, I was very pleased with this item - but after three days, the outdoor portion stopped working and I was ready to return it. However, I did some research on these types of thermometers and in most of the directions, it said something about using Lithium batteries if you have extreme cold. Well - since we had been sitting at below 0 temps for 2+ weeks, I decided to try the Lithium batteries - I now have a working product and am very happy with it - I think the folks marketing this and writing the instruction manuals should add this piece of information as well. That's the only reason I didn't give it a 5 star rating - Just a heads up.
