I bought a new Martin Bengal last year. Decided to spring for a set of strings/cables. Had about 200 shots on it by the time the new ones came in and had adjusted/turned the peep a half dozen times.

Put the new ones on (Sorry don't know the material..blue and brown and "as many strands as will fit in the cams")

I've adjusted the peep twice. They were within the first 100 shots. I'm probably around 6-700 shots now.

For $40 bucks...the peep issue ALONE is worth it to me.
