I've been using this for years. I have a bunch of used boxed on my shelf in my office/studio of sorts.
I won't drag on for too long but bottom line:
I have never broken a set of these even if I bashed my strings like there was no tomorrow. They last like no other string I've used(A few other brands kept breaking on me). If cleaned and wiped down after and before playing they will be faithful in delivering a nice tone for quite a while!
Recently purchased new acoustic guitar and encountered a new problem. Each set of strings I purchased seemed to have a really high tension along the guitar. String bending was a problem and even holding down the strings near the neck was also problematical. A little bit of research showed me that these strings had the second lowest tension of all the Martin strings (extra lights were lower still), I purchased them, put them on and my high tension problems disappeared.
