We do, but I've never had a WWVB clock work for me in North Carolina. I've tried a few of them. The US is a big place and for whatever reason, there aren't that many clock signal transmission towers (AFAIK, the only one in the US is in Colorado).

I'm in WV, but could only get my clock to set itself when put on the correct SW-facing wall.

Obviously it defeats the purpose a bit if I need to move my clock to a different wall and wait 12-24 hours for it to set itself.
