Nice tone, but not so much on reliability
I bought two sets of these and went through both sets in a month. The tone these strings had when I put my first set on was fantastic! Three days later, my D string broke. So I tapped into my second set to get the D string then my A string gave out the next day. Dipped into the new set and the next week the B and G were gone! I'm known to have a heavy hand when it comes to playing, but I couldn't keep these DRs on my guitar long enough to enjoy the great tone. Thought maybe my guitar was the problem, but I haven't broken a single Lifespan Martin yet. I use DR strings on all my electrics, but sadly I couldn't recommend these. Just my experience.
