The best on the market in that I have tried.

i really loved my chi, which my husband bought for me for christmas until it had a short circuit . i had to continuously move the cord so the led light would turn on so it would work, i eventually bought a new flat iron at marshalls made from the same manufacturer (Faruk) called Biosilk. It works good too but nothing beats the Chi in my opinion. They need to do something so the cord won't mess up. As far as the price it's way too high but well worth it. I would buy it again.

The REGULAR Chi irons are fabulous! I have been using them for almost 10 years. Each one usually last 3 years or so before it stops heating properly. Fortunately when that happens, you can just mail it back to Chi headquarters in Texas for like $30 and they will send you a brand new one! My brother bought me the Chi Nano when it was time for a new one a couple years ago--it was great because it heated up so quickly and had a REALLY high temperature--but I went through 3 in one year. The overall quality of the product is terrible because it doesn't last, although their customer service has been very understanding and helpful. I now have the Chi Air--it seems to work similarly to the regular chi.

I purchased a Chi for my daughter who was 16 at the time for a Christmas gift. I got a great deal on during a black Friday sale at Sephoria and it was what she wanted badly. At first I thought I could not believe that she wanted such an expensive hair straightener and thought what could possibly be so great about this straightener. She opened it on Christmas morning and was so happy. I wanted to know why it was so great, so I tried it on my own hair. Wow it is an amazing product. Like many others have said it did a fantastic job at making my hair straight and it did not have to be straightened again after work to go to dinner. The style stayed all day long. I have to say that it has been well worth the price as she uses it daily and it is still like new. If I would have bought her a cheaper model, I would have had to replace it by now. I think it is a wonderful product that perfoms well and is very durable. :)

I miss my Chi!!!! I had a Chi straightener for year until it finally gave out. For Christmas a family member gave me a new straightener, but it's not a Chis and doesn't work too well. I'm saving up for a Chi! What I liked: The 1" was a good size. Big enough to get through thick hair quickly, but not too big to mess up my fine hairs at the scalp. Heat! The Chi got hot, and with thick course hair I need heat to get straight. Price. It's not the cheapest out there, but for the money the value is the best.

I have long hair that is thin with a slight wave- Chi is the best product for my hair.

This used to be my favorite straightener until I discovered the Sedu. Much better! The Chi is good, but is not the best out there. I have converted at least five Chi users

I absolutely love mine. Greatest straightener ever!!

I have super curly hair and have never been able to straighten my hair until I used the Chi! It was totally amazing, my family did not recognize me. Now I have options for styling my hair that I've never had before.

Works very well w/ just a couple swipes down my hair.

The CHI is a fantastic styling tool! However, remember to only go over each section once and BE SURE you have some sort of heat styling product on prior to use. Also, make sure not to use it on wet hair, and and always condition in between styling. As a stylist, I've seen many clients come in with severely damaged hair because of improper flat iron use.

I have curly hair that I blowdry and flat iron every day. For years, I would buy the cheaper $20 irons only to have them completely break after a few months. I would guess, on average, I was spending $60-$90 a year on irons because they would keep breaking (and of course, because they were cheap they had no warranties). I decided to plunk the $100ish on a Chi turbo and I've never looked back. I purchased it back in 2006, and it's still going strong this day. No replacements!! There are several Chis out there and I went with the Chi Turbo because it not only heats up extremely fast but it also has a dial for you to change the temp so it doesn't feel like you're frying you hair as much as a set-temp one. I know it's a lot of money, but it's totally worth up. Add up what you're spending on low quality irons in a year and for how many years you've been doing it. Enough said.

I absolutely love my CHI flatiron!! I have used and returned several other, cheaper brands and will never go back. I use my CHI daily with no damage to my hair.
