I've bought this pick with a very specific use in mind; I am a guitar player who has recently acquired a bass guitar, and since I have nails on my right hand, using my fingers to pluck the strings would produce the sound I am not really after, besides it would be detrimental to the nails themselves, so I was exploring other ways of trying to get the sound that's closest to the sound you would expect to get when playing the bass with fingers. I've thought that using heavy and large picks for such a purpose would be better than using the regular ones, but that theory did prove wrong in this case; these picks, even though they are bigger and heavier than the regular ones, they have sharp edges and produce a really bright and unpleasant sound on bass, so it kinda puts you back at the square one sound wise. Actually, in the meantime I've found out that using the regular 0.88mm picks (which I normally use on an electric guitar), but only turning them around and picking with the round side of the pick works much better than these ones.
The pick seems to be quality-made, it has a good grip and it feels durable; I can imagine it not wearing out for a long time (undoubtedly someone who has been using it on a guitar for a longer period of time will have much more relevant opinion about that), but since I've been reviewing it explicitly for my purpose, hence the two stars in Total.
