Check out my other ultex review for their thinner picks. These are the same except stiffer and clickier. Definitely inferior for acoustic strumming, but barely different on electric. The extra few millimeters make them a less effective toothpick for people with overcrowding. Since they aren't an effective dental tool I am docking the 1mm picks 1 star.
Clear tone, good pick attack, because of the sharp tip it makes playing leads easier but because its still a full size pick it makes playing heavy riffs easy as well. The grip is not so good though, especially if you have sweaty hands.
