Whatever I say about this device will be little!
I bought it for my mother. She uses it 2-3 times a week and she is thrilled with the result. It doesn't damage her hair, it dries them (because she uses it when she takes a bath), it doesn't tangle the strands but straightens them to the right degree.
She has told me that she hasn't seen a better electric hairbrush.
Even though it is Italian, it seems worth it.

It's not worth the money, the previous one I had may have been cheaper but it was much better.
Update: just burned after 6 months of use.
