Yes! One pass

It’s only one pass and enjoy your silky hair. Just like everyone said, it takes u less time to get your hair done. I always straighten my hair before I sleep and cover it, then the next morning, my hair is straight, silky and no frizz at all and it lasts until the following wash.The reason why I gave this product 4 out of 5 is that i have noticed dramatic hair loss after the first and second use. I only adjusted the temprature to 240 as I do have fine hair but my hair got a little thinner since I started using this flat iron. I am still amazed how could a 240 degrees cause this massive damage!I would have really liked to give this product 5 out of 5 as it really does exactly what it says but I am not sure if I can recommend it to all hair types!

great straightener!

My hair stylist recommended this straightener to me, so I decided to try it out. The plates glide over my hair effortlessly and do not snag, which my last straightener was doing- causing my hair to be damaged. it heats up very quickly and has different temp settings. The only con is that it takes me more than "one pass" to get my hair straight, but then again I have coarse, curly hair.

sublime!

It wasn’t what i expected, it was amazingly better! i have baby-fine hair and had purchased other flat irons that just wreaked havoc on my tresses. i was super excited to use this for the first time and was pleasantly surprised at the quality of the iron and the bone-straightness it made my hair. i couldn’t be happier with this product. i was not looking forward to paying this much for a straightener but it was well worth the investment especially since i bought a cheap knock-off from ebay that left me broke. thank you for reading my review, you will love this product.

Like everyone says, it’s great!

Just got the OnePass 1″ straightening iron and it’s exactly what I wanted.It’s fast and easy to use, heats quickly and evenly – and best of all, gives me amazing results. I can do my medium-length hair in under ten minutes, and besides the straightening effect, my hair seems to come out healthier looking and silkier. Definitely better than other irons I’ve tried.Otherwise, it seems well made and pretty rugged. Love the controls that let me home in on just the right temperature, and that the cord is long without getting in the way too much. Definitely worth the price if you’re looking for a terrific straightening iron.

Works well

This flatiron works really well. I needed a new flatiron because other flatirons were not doing the trick. This works fast and straightens my hair without frizz. It cut my flatiron time in half. My hair stays straight. I bought it after reading other reviews because I did not want to spend a lot a month another CHI that does not even work that well.
