I have been using these picks(along with my Jazz 3's) for quite a long time now and they have served me great. Before these, I have been using similar shaped handmade picks which cost around 10¤ per piece, and I must say that Harley Benton's PH1s compare very well to those, both by feel and look..They also cost much less(2.90 for 2 of them) so i'd say its a great deal.
They are shaped very well, curves for thumb and point finger are shaped and sized perfectly(at least for my hand), so you can get pretty good grip.
The only drawback is that these picks wear out pretty fast, but that's not a huge deal, especially for this price...I would definitely recommend them to everyone!
Rock on! :D
