First of all, I completely agree with you. The Tyrolia bindings are a bad copy of thye first concept of Marker products.
Secondly, don't trust at all about the positive reviews about Head product in internet social network or forum when you don't really know the author.
Head has a lot of "hidden" promoters that put good reviews and comments in social networks. At least this is the situation in the European forums.
Thirdly, I bought an Adrenaline and after 2 days it starts to lose the settings and during a descent I lost 1 skis without any reason.
Your first post is telling folks NOT to buy a product based on anonymous reviews by people on the internet, then give a negative review.
That's ironic. I like you.
