Finally I found the guitar strings hold quite a long and sound life long. Since I have relatively sweaty hands I had to uncoated strings often change than I liked. But at this Elixir strings this is finally over. Some might find the strings may slippery than uncoated strings, it occurred to me this does not adversely affect. Positive is the strings to play softer than others. The price is the quality of the sound and especially the durability of the strings quite appropriate.
