Lee,
We always have a dozen or so of these in our closet, wrapped in bland paper so that it can be an emergency house warming, birthday, or other gift. I see no reason why you could not use them for Christmas. They are cheap, and EVERYONE I give them to laugh at first, then a few weeks later they say "Hey, I actually used that thing and it works. Thanks."
