This is an interesting pick. The pick is VERY sharp and therefore I think it hits pretty good the strings, however I must say that the "machining" on the bevel of the pic was not that good in the one I received, so there were some "bites" on the edge. If I try to sand them, I will remove some of the sharpness, so quality is just "okay".
The grip is very good since it is so big and the shape is actually also pretty good. I will need to test it further to check for the durability.
Regarding the price, this seems to be overvalued. 6 euros for pick? I think 3 might be reasonable.
However, I am staying with the Petruccis signature pics for the moment. I try the screamer from time to time, but it is still not my number one.
