The pans of the company Wool are initially very good indeed, the anti-adhesive effect is great. Unfortunately, the pan is used regularly but after about 3 years back. The non-stick effect is virtually non-existent and you can no longer fry without letting it burn / sticking. The company wool does not feel its guarantee obligation as human error (wrong fat, too hot etc.) are subject to and referenced "tar deposits". If you are then still insists on warranty ignored. Lest times according to some independent forums on the I-Net, because this approach is often confirmed.
Conclusion: Expensive pan that you get with other manufacturers in quality at significantly lower prices.
