Anyone on here ever use one of these? After being harassed by my mom to try it and then coming down with a cold in the past few days I finally decided to pick one up and give it a go. Definitely was an interesting experience. It really didn't feel like described and I can't figure out why - maybe the wrong water temp or wrong angle... I don't know. Definitely didn't work as well as I was hoping it would. Anyone else ever tried one?
