I'm thinking you saw a Corioliss
It does curl if you do it right. Just have the girl show you and then ask to do it yourself so you can see JUST how to do it. Once you get the hang of the curlign it isn't too hard.
I have 2 of them One pink and one black.
2 things.... do not pay the asking price!!!!! All of the kiosks have a list where they can seel it for less if the person looks like they are going to walk away instead of buying. Tell them you want there best deal and look like you mean to WALK! ALSO if you buy 2 (maybe take a friend) you will get a lower price.
The one you are talking about is BEST in my opinion. They actually have 3 kinds. The one you are talking about is SUPER lightweight and does the curling also. Don't pay more then about $150 for it because they CAN come down that low. Also make sure for that price you get the newer version with the longer cord and on off switch. The older model doesn't have a switch.
