I thought I'd give these coated guitar strings a try since any other strings I try seem to go "dead" very quickly. Someone told me I have acidic fingers, although I've never heard of that one before. These strings have a nice tone to them straight out the packet and have lasted very well so far. I mainly play with my fingers so can't say how the coating would wear using a pick.
So, great strings at a good price and last very well.
