I've tried brushes before that claim to straighten like a regular straightener, but I thought I'd give the comb a shot, and I could always return it if it didn't work for me. Well, I absolutely adore it! I did use a smoothing spray, and I didn't take as much time to go slow and section it off as I could have, so it could probably be even smoother and straighter if I put in more effort. The only thing I don't like is that the buttons are right where you hold the tool to use it, and it's easy to accidentally lower the heat or turn it off. I've noticed this with most products like this, though. Not a big deal, just have to be careful not to accidentally change the heat or turn it off. But overall, super happy with it! It's an awesome product, and I love all the accessories that come with it!
