I've been using it to play 5-string bluegrass-style banjo. I got a few different kinds because I found that the brand I had been using weren't very durable. The quality of this pick is great though. However, the special texture on the pick's surface makes the pick very noisy in terms of pick noise.
It should be added to this that this pick isn't thicker or thinner than the other brand that I've been using, it simply has a different kind of surface and may be of another type of plastic. All in all, it's far too noisy for banjo, may work for dobro, I cannot say.
