I'm on my second day. After Amtel. While satisfied "like an elephant." There are fears that they will quickly wear out and go in bubbles, but it also depends on luck on the road and driving style :-) With its pros: I compare with Amtel: MUCH quieter, holds the road a little better, lighter. The price is slightly higher than Amtel, but in the same price category. Cons: Thin sidewalls, the slegant shakes when cornering, they say that it does not hold holes, I'm afraid so, but there is no confirmation of this yet.
