Totally worth the money.  I originally bought two pair, however I am going to buy 5 more.  Sooooooo comfortable.  Eliminated chaffing the moment I put them on, however the will bunch up on your legs with tight clothing.  A pair of my jeans are a little tight, and with those the did ride up my leg. However that being said, if you wear them with compression stockings or tights, they do not, interesting!!!  I bought some mesh laundry bags on amazon that I use to wash them in, and there is no pilling so far.  I just wash on cold and then let them air dry; takes about an hour with the fan on at 70 degrees.  They also let your junk breath incredibly well, and they somehow wickens moisture away from it, and keeps it cooler as well. So glad I found this brand
