Well I saw them in many cars and they kind of look the same. I mean all the treads of all the 'euro' series... euro glide, euro star and euro kontact. The grip seems decent and much better than the old XP 2000 II series , but in no case comparable to any of the other brands of the same tyre size.
For your questions:
Did someone use it ?? - no not personally
Price Tag ?? - 2800 per tyre
Can be compared to Dunlop, Bridgestone etc - not at all
