I must admit I bought this waver thinking it was the same as a 3-barrel curling iron... my mistake! It definitely is more like a large crimper. That being said, it works really well! Heats up fast and HOT. I felt a little like a lion at first, but after a half hour the waves relaxed and I loved my look. The best part was they lasted well into the next day, so I wasn't embarrassed to go to breakfast with bed-head. If you are looking for 3 ROUND barrels, don't buy. But if you want big "Z" waves (not S, IMO), then this is a great product. My only complaint about the design is that it gets pretty hot right where I have to hold my fingers. It doesn't burn you or anything, but I'm surprised they didn't fix that.
