works good

These are easy to use and extend the life of my gut string.

cost is good as reasonablly priced refill strips of savers are available. did not work on a soft multi-fillament synthetic gut. savers seemed to be sharp edged and initiated fillament breakage that led to string breakage as quickly as without them; don't know how they would work on gut, or other string sets like hybrids, where they might prevent one string type from wearing into the other.

Price was low, and the product works. My purpose is to avoid string breakage. I use an out-dated Big Bubba and the frame can implode during stringing.

I tried the 3 major brands. This is the worst. Material is soft and thin. Wears through immediately, so strings are rubbing each other within 2 hours playing time. Gamma is the only brand that comes hard and thick.
