Water Pic (Palo Alto, near Cal Ave)
My dentist wanted me to use one of these. I tried using it maybe a dozen times and just never stopped hating it. It's in perfect working order. Please note, I will leave this post up for at least 24 hours (until probably Wednesday morning) at which point I will chose from the people who have asked after it by drawing names out of a hat.
