Low quality.
"The sadness of low quality lasts long after the joy of low price."  Very cheap construction--low quality. It would not fit properly in my shaver, or stay put. I had to deepen the retaining grooves in the base of it by using a precision jeweler's file, and make other "adjustments" to the plastic body in a similar fashion so it would fit. The cutter head does indeed seem to work adequately.
