I bought this string set only for exercise.
It is not constructed for concerts, however, it was not bad for everyday jamming and playing.
Stabilization of tuning takes longer time than premium strings (10-12 days), if stringing is not carefully done.
5 stars for price/value, and it was better than expected.
Very good reserv or etude set. It works in jam play, and very solid.
