Query: Two Stars to Give it a Chance

I've been using this for three days now. I was a big fan of the original Caruso steam setter that required the addition of salt. It gave great curl and I got tons of compliments on my hairstyle back then. Style lasted all day. I just bought this, excited at the prospect at reliving those good hair days. But, alas, I haven't found the secret to "curls that last for days" or even hours. I've even tried leaving these things on for over 20 minutes and I've tried having completely dry, unwashed hair and leaving them in for 20 minutes. Not great curl and it doesn't last If something changes, (it's 12/20/08 today), I'll get back to ya.
