Best straightening iron I've used

I've been straightening my curly hair for about 5 years now, first I used the conair steam straightener, then I upgraded to the Chi ceramic iron, which worked pretty well for a few years. Recently I noticed it was not working as well anymore. I had seen some good reviews on the Sedu iron, so I decided to give it a try. It works wonderfully, smoothing my curly frizzy hair better than even chemical straightening, which I've had in the past. I would definitely agree with their claim that it makes hair 3 times smoother. The cost is high, but worth it. Hopefully the iron will last several years to really get your money's worth.
