I purchased the sultra "wicked" iron.I have fine,thin color processed hair,so I have to be careful what I used.Based on good reviews I gave it a chance.It has a nice,sleek style and box..heats up quickly,straightens nicely but makes hair very flat.I always use CHI heat protectant,and within a week my hair was noticeably more damaged and fried from the iron! If you have thin hair,stay away from this..there is no temperature control,which I discovered the heat is 375 degrees!!! I returned it and will not use it again!

Great iron, heats up very fast and really is one pass. My hair is wavy, thin but a lot of it and longest layer is to mid-back. Doesn't snag any hair either. Be sure to use a heat protectant!

I purchase a flat iron every few months. I've tried most of them, a few I've purchased multiple times. This is the most AMAZING flat iron to date. I am absolutely in LOVE! Due to the fact that my haircuts are so expensive, they are far and few in between (yes, after 6-8 months I still get compliments). This flat iron has brought lots of compliments in a few days than I get in a few months. Not that I just want the compliments, but this is from people that see me fairly often. I am sooo happy. I did return the Bombshell wand, another review for later.

Bought this to replace a Sedu Pro Ionic Ceramic Tourmaline Iron. Thought I'd review since that was a popular iron and I couldn't find any comparisons.
Let me start this one with my hair type: medium-thick, somewhat tightly wound, curly italian hair. Lots of frizz. Tons of hair. Very dry. Color-treated. Long. Split ends. Lots of work to get a look that I'm happy with. Babyliss, Hot Tools, Chi, anything "basic" ceramic or gold does nothing good for my hair.
I had been using the Sedu 1 1/2" flat iron after seeing great reviews of it on Folica. Here's the story of my Sedu:
I got my first one about five or six years ago (whenever they first got big) and I loved it. Gave me a gorgeous look, was easy to use, and I recommended it to everyone. I took it to Italy with me on a trip in June 2010 and plugged it into my adaptor... it buzzed once, and then died. Should've known better. I promptly ordered another so it would be there when I got home.
Something about the new one was different. The design had changed minimally -- it now had a swivel cord (nice) but no longer had the little rubber hanging loop that it used to have (not nice). I noticed that the plates weren't matching up as well as they could have. It still felt hot but it seemed like I had to pass it over my hair more times to get it straight. It felt like my hair with my 2nd Sedu wasn't resisting humidity as well as with my first one. It didn't look as good (I compared photos and it's such a big difference in shine and health). I wasn't happy. It's almost like -- and this is just my uneducated guess -- that maybe Sedu made their product a little cheaper with all the demand? It took longer to do my hair and I was getting very frustrated with it.
I heard someone talking about the Sultra Seductress and I thought I'd give it a shot since I didn't want to use my Sedu anymore. I'm VERY impressed by it. I only have to do one slow-ish pass on a normal section of hair to get it straight and it really looks better than it did before with the Sedu. It's easier to use. Takes less time. Hair feels super soft. It claims to "seal" hair while it straightens. I'm not sure about this, but my hair at least looks a little less split-endy.
The design: It's got a rounded outside so you can do flat-iron curls with it. I probably won't use it for this, but it helps if i want to turn the ends of my hair in/out. The Sedu was too flat to do anything but straighten. Comes with a 2-year warranty and heat protect pad. Heats up in seconds and has automatic turn-off if you don't use it for 30 minutes. Good to know since I'm always paranoid about leaving irons on when I leave home.
If you're choosing between the Sedu and the Sultra, I'd say go with the Sultra, especially if you have difficult hair. I suppose the Sedu is fine for you fine/wavy-haired girls who think you need a heavy-duty iron ;) but for me, the Sultra is a good investment.

I purchased two of these. One for home to curl my stick straight hair because curls from curling irons don't stay. The other is for work, I have notcied my GHD sometimes takes up to 4 passes on my course haired clients. This iron is amazing for smoothing hair to a glass like finish, and creating bouncing curls that my other irons never even came close to. One word describes this iron-amazing.
