Here are two examples. Now, when talking with my American, British, and German friends about these, the Americans all said that it was a UK, western European thing and that Americans didn't use them. Personally, in my household, we've gone through a few because we've used them so much. The American's just said "well, maybe you're just more British and fancy than the rest of us." I was shocked to hear that my fellow American's never had one in their homes in the States.
So here's my survey: leave a comment saying what part of the United States you are from (or what country you're from if you're outside of the US) and if you've had one of these in your home. You don't have to leave your name. I just need location and if you own one or have ever owned one.Thanks!
