I bought these to put on a Yamaha APX500II after a few years of using Martin M140 strings. I found them to sound very full and clear, particularly through the pickups in the Yamaha. The level of tension they provide suits the way I play, which is usually pretty hard being a metal guitarist over all else.
To me, they feel familiar, having mainly played electric guitar, but with a pleasing full sound that you really don't quite get with a clean electric guitar!
The strings show no corrosion or damage out the hermetically seal packaging, and were easy to put onto the guitar. They lasted a little longer than many other strings I tried, particularly given that I play fairly infrequently, leaving the strings open to more corrosion from the environment than wear on contact with my hands!
Overall a worthwhile buy, I'd consider them one of my top acoustic strings to purchase.
