First things first, the picks are amazingly versatile. They really can do anything, and wont slip, ever. Max grip is not a joke, it works (although sometimes the surface is unpleasant to hold).
The shape of the pick should be familiar to anyone who has used Dunlops picks before, but the picks are slightly fatter than most at 1.14mm.
The picks are no Ultex Jazz III's, but they sure can take a beating and last very long in use. I've never actually managed to wear one out and have used the picks for around 8 months.
The only con is the large size, so they won't play as fast as they could, but thats just my personal preference.
All and all, the picks are amazing at a low price point, and really work for anything.
