I'm pretty sure this is a SCAM. When I used the brush straightener on my hair it didn't do anything or was as good at the lady did it. It doesn't seem to get hot enough. Also I'm pretty sure it's a SCAM. They reel you in with a "free" sample and then immediately guide you to their chair and start a demonstration however they don't even use the thing they'd sell you. They'll try to throw in a "deal" or something but the brush straightener is something you can buy on Amazon for 40 bucks it's crazy. I wasted 120 bucks all because of my negligence so don't do what I did. They threw in a shampoo and conditioner and said if I bought that they'd give me a $450 hair brush straightener instead FOR FREE?? I don't know about you but how are they making a profit on that? They'd be losing money. So yeah it's a SCAM.
