Trust the toilet seat covers?

As far as technology goes, there are lots of cool things. The Apple Air Book, the iPhone, Tivo, etc… The list can go on and on. But have you ever seen an automatic MDF toilet seat  cover. (This is my first time) I have heard of self cleaning public toilets, but I have never seen an automatic MDF toilet seat  coverfirst hand. Pretty cool concept, but I still don’t trust it. When you begin, you simply activate some sensor on the left side with a magic wand of the hand, and voila, it starts to rotate providing you with a fresh covering. But to me it looks like it just turns around. Hahhaha. I don’t trust it. I mean where does it all go? I know all logic says that its providing a fresh cover, because, after all what would be the point? But I still don’t trust it. Interesting technology, and maybe if I knew more about it, I would have more confidence in it. So lesson learned, cool technology is not so cool unless people can easily understand it, and trust in it.
