By far the best feeling picks I've ever tried. Great for fast playing and pretty good for strumming. Unfortunately, they the tips wear off pretty quickly. after 4 months of semi-regular playing, the got blunt and soft. This doesn't affect the playability yet, but it might in the near future. Also, they are pretty smooth, so they don't grip as well as some other picks, but it's not as bad as it might seem.
Overall, the picks are very much worth trying, despite the flaws. But if you happen to fall in love in them as I did, expect to buy new ones every now and then.
