It's taken me quite a few attempts to get a nice effect - I advise going on you tube to check out a tutorial to get your technique right. My main issue is that I have thick hair so it took longer than the videos I saw. Ultimately it's a nice effect, and will be quicker with practice, but not something I have time to do on a regular basis.
The glove included is great to stop burning accidents when you're getting the technique right. My only issue with the product specifically is that I kept hitting the temperature control when I was using it, turning it up higher than I wanted it, because it is in the way. Otherwise it's excellent value for money.
