Review (1/5): Died after less than 5 uses
Update 7/2017
Incredibly disappointed. Below is my original review. Since that time, I have uses the product less than 5 times before it stopped working. I was originally very pleased with it, but now there is something wrong with the wiring. Shortly after turning it on, it will shut off and it's not from accidentally hitting the off button. That is also another flaw of this product, you can easily accidentally turn it off. Not worth the money.
Old review in case mine is one of the rare defective products:
I can't say enough about this amazing product! I can straighten my hair in less than 10 minutes including the time it takes for the comb to get to 230 degrees Celsius.
I hated using flat irons because I had to section out my hair very meticulously, comb it through, the pass the straightener. The process would take me 45 minutes to an hour to straighten all of it. And I still hated it because it looked too stick straight, I couldn't run my hands through my hair well, it seemed to tangle easier. So I started to round brush and blow out my hair instead because it looked more natural and could run my hands through it, but it took about the same time. I'm lazy so I did this very rarely.
With this product I only have to section three layers and pass the brush twice through (once with the hair lying on top of the brush and then brushing through like a normal brush) and it's perfect. I don't have to coordinate a comb and the flat iron or blow dryer, it's all in one device. I'm so glad I found this product!
My hair is about 6 inches below shoulder length, medium-thick, wavy. It works well because my hair isn't too wavy at the roots. If you have very curly/wavy hair and need to straighten starting at the roots, this product won't be able to easily achieve that. For my purposes, it's the best hair tool I have ever used!
