I normally dont write reviews because Im too busy, I forget to, or whatever... However, this thing deserves a 5 star from me. I love it so much that I also got one for my little sister who loves it as well.My sister has mostly straight hair but with some wave to it, and she likes to have it sleek straight since it looks better, but she is usually tired and busy from raising my 2yo niece. What used to be a subtle change that took easily 15-30m, is now just as good within 5m at best.Now for me I have very thick and curly hair. Usually when I go to straighten it, I have to partition each section and go one by one, usually passing the iron 2-5 times per section. It takes on average 45m to get my hair to sleek straight and even then it was never quite perfect. The lines from flat iron, the bits that stayed slightly wavy horizontally in the iron, and it being hard to reach spots. Now I can have my hair from curly to being SLEEK straight within 10m and that includes the brushingI genuinely love this thing and I was expecting to be disappointed. Im not even sure how many straightening brushes and combs and driers that I have tried, and all of them would at BEST get my hair straight enough that I could grab the flatiron and finish the job.It is very soothing because it feels like brushing your hair, and it is fully enclosed so you dont have to worry about burning yourself which is something my sister loves about it since it makes sure my niece doesnt accidentally grab it without my sister having time to react and then her getting burned.Again Ive been disappointed by every other version of this out there and had resolved to the fact of flat ironing it for 30-60m was the only way. Then I took a chance on this and am loving the extra 20-50 minutes I save while getting results even better than my flat iron.If you want to have a bang flip sorta thing, you may have to crack the flatiron out for that one. At least I havent been able to really nail doing that with this thing yet lol.TLDR I took a chance on this thing while expecting to be disappointed, but now I think you should take a chance on it too because its blown me away
