Any knock off club is only worth 1/2 its value. They rarely have the quality to give you any of the needed consistancy in swing weight, loft, lie and construction. This sesults in verried
clubs being quite different from each other.
They may look like the club that are trying to copy, be there is no way it will play like them.
If you are worried about cost, it is always better to get a used set of an older model of the real thing then to get a knockoff of anything.
