This is my second set of replacement shaver heads for a Norelco 5000 series shaver.  The set that came with the shaver and the first replacement set (also from Norelco) were marginal at best.  Took forever to shave (and I have a relatively light beard) and the shave was never close.  These are the exact opposite; shave close, comfortable, clean.  Highly recommended, particularly for the price.
