From this article, I can only advise .. This ridge looks so cheap and nasty from manufactures that you can in the store immediately hands off. From the beautiful image, one should not be fooled, the reality does not look so beautiful. Furthermore, the hair comb arrived even broken. When I had taken him out of the package, with one point is directly dropped.
For this product you can just say "no thank you"!
Something positive I would have: The order arrived on time.
