The toilet seat (Pureflush) is such a unique product. It's a 21st century invention. I went to the website (www.pureflush.com) and there are published scientific papers about toilet aerosols that blew me away. I like the carseat also but I believe Pureflush will save more lives every year. It's so clear now that I've read the blogs and compared all the other inventions. I hope the pureflush couple get this on the market asap. Should sell millions.
