Disappointing. Don't get suckered by the rock stars.
Sounded great for the first week. Then all the bounce went away, and they got dull and lifeless. The low strings became impossible to get any tone out of- too thin. I could hear the slap but not the low note itself. The high strings were OK, but not spectacular. Finally, I broke the A string with my bare hands and the strings weren't even that old. I didn't know how much these strings sucked until I replaced them with medium gauge from a different brand. Don't get suckered by famous endorsements, these strings are a disappointment.
