Can not understand the hype

The brush is comfortable to hold and the massaging action on the scalp is actually quite pleasant.
With drawbacks.
But the bristles bend with my thick hair even with minimal disruption. The brush is not ziepfrei through his hair and the tips of the brush add right pain to me. And if I do not give night and to come close to the hairline, it really hurts. Or even to the ears when there times over accidentally slips.
Small Torture)
I have a very sensitive scalp and (pressure-free, mind you!) After the first application has left it marks on my scalp, which have partially correct weggeratscht my coat and the next day flaked properly, aching and itching. As fine scratches.
As I said, no pressure! Mere slip of lace, nasty sting.
Shine in your hair? No, not what a real hair brush can not get better.
Volume?
Yes kar! Charged and overhead every hair fluffed up.
Very unangehm.
