Decent, But Not A Miracle Worker
This is a pretty good curling iron, excepting the learning curve, but it still doesn't beat my $11 Conair Hot Sticks iron. The Sedu is made for thinner hair than I have -- it takes an hour to curl my whole head, because smaller sections look much better. If you don't have my hair type -- coarse, thick, frizzy/wiry Asian hair that doesn't like to curl nicely -- you will like this iron.
Lasting power is pretty good -- I get a couple days of curls looking decent (My scalp is really dry so I don't wash every day). With the Conair, curls last three days. Hot rollers last the longest, provided I prep my hair well.
This iron is much easier to use than a clip iron, as you don't have to work to keep a dent out of your curls, but it's really overpriced and takes forever. I'm keeping it for now but it doesn't really fit my hair or my lifestyle.
