yay for engineered obsolescence, its just good business
It is what it is.
It has its good points and its bad points.
The good thing is that the rotors are only as good as they need to be which means they are as light weight as possible, and usually less expensive than one designed to be machined down and reused. Light weight = more fuel efficient. Low cost = cheaper to replace.
The bad thing is they are a one shot deal and aren't thick enough to be cut down and trued. Also, some mfgrs. take the concept of "only as good as they need to be to the nth extreme and make them too thin and more prone to warpage.
