I watched the whole 30 minute infomercial on this thing (yes, I am a loser). It looks nifty, lives up to it's claims, but I ask myself this...How many people have died/been made ill by the fecal coliform bacteria lurking in their bathrooms, waiting to wreeck havoc on your GI tract? I don't know of any. If it makes you feel better about your oral hygiene experience, go for it. I can't justify the 50 bones it costs.
