Review title is Stubble Trimmer [SEP] This is a replacement for my prior Norelco trimmer and works about as well. I was not happy to find that the prior one failed to hold a charge after a couple of years and the battery could not be easily replaced (not replacable per Norelco). Thus, I face the same fate with this one but have not found another that collects the whiskers (mostly) and thereby minimizes the mess. [Addendum to review two years later. Now it makes a sound like a piece of metal is floating loosely inside and grating against moving parts but it still works just fine.]
