Product review (2 stars): I liked it until it started showing me "LO"
I liked it until it started showing me "LO",which I took to mean that it needed new batteries. I installed 2 brand new batteries, and it still showed "LO", so I tried 2 more new ones, same thing. I tested all of these plus the original ones on a good battery tester and they all showed that they were good. So the thermometer itself must be defective. It wasn't expensive, but needing to replace it every year or so makes it a poor bargain.
