text: I'm not a fan of knockoffs and I believe there are some differences.  It may be in the material or the construction of the club as well as the shafts used.  If you are starting out or haven't golfed much they would probably be ok.  I would strongly recommend going to a golf pro shop and play with the original clubs first then purchase the knockoff clubs. This way you will be able to determine any differences, and hopefully, the internet business you will be dealing with has a good return policy.
