I really wanted to like this piece. It looks great, fits nicely in the small area we have above our doors for a clock and tells the temp which is the very first thing I want as soon as I know the time. The first one I bought worked great for over a year until the transponder got lost in a storm. The second one never worked at all. I give LaCrosse credit -- they replaced it immediately. But that third didn't work either. Spent lots of time with Tech Support -- who were very helpful and responsible but couldn't get it to work. Then, I matched the transponder from the second with the third clock and it worked! For about 3 days. Then it wouldn't work either. No combination, no matter how many times I reset and no matter how close I put the clock and the transponder would work. Finally just gave up on it. I have no idea why its so tough to get a good signal to travel only a couple feet (it was that close).
