Query: Very itchy and hurting! Not recommended!

All the four or five stars comments led me to the wrong way. How can so many people give irresponsible comments? Here I try to give you my honest opinion about this product. Let me reminder you with its material first: 45% wool, 25% Angora, 20% nylon, 10% elastic. It does keep your knees warm but also makes them itchy. Wool definitely makes skin itchy. In addition, it will not stay in your knees like the picture shows. It gets all wrinkled and makes your knee hurting after you wear them for a while. For this price, I expected much more than that. I am contacting the seller now and see if they will take it back. I'll not recommend to anyone. Hope my comments will help you out when you try to choose the right product.
