Replaced the the original factory chain that came with my Craftsman chainsaw. This chain takes out bigger chucks and not saw dust like the one that was on it new. Plus hasn't kicked back on me once after over 2 hours of cutting. The key is to sharpen the chain at least ever tank of gas.  I Ordered an Oregon 5/32- inch file from amazon and takes only 5 minutes to sharpen the chain after a couple minutes of practice.
