Design Flaw........
The performance of the brush works great. However that design and functionality needs to be improved upon a lot. All the temperature buttons just happen to be in the thumb grip area where you hold onto the brush and you can't help but change the temperature constantly without wanting to. This, in my opinion, is very dangerous because you can set it to a low temp and not realize until your hair is burning that you have inadvertently change the temperature way way higher.
