FINALLY. I found a straightener that can do everything I need--calm my unruly, frizzy hair, and create a chic, and polished straight look for my hair. I recently began to use it to curl my hair too, and it does that perfectly! I always use it at the highest setting, and put a TON of product in my hair and still the iron has lasted me a really long time and is still incredibly effective. I straighten my hair probably three times a week, and before I bought this iron it used to take me an hour, now I'm down to just thirty minutes (I wasn't kidding, my hair is a mess!!). I LOVE this product, and would recommend it to anyone!
