This was a replacement for the factory model. The original has been in use with countless chain tensioners for 4 years and has never had a problem. The only reason I replaced it was because it was lost. This lasted a maximum of 10 pulls before a tooth broke. I don't think this is a reflection of the seller just parts and what I think is poor quality on the part of the manufacturer.
