Junk
I bought this because I broke the plastic guard for the styler that came with my Phillips/Norelco YS524.  This fit my shaver, but it is *not* a replacement for the one that came with that kit. First of all this isn't adjustable, which I suppose is my fault for not reading the description or reviews more closely. More importantly, this trimmer was weak to begin with, and only got worse. It trimmed about a third of my face before it became too frustrating and upsetting to continue. It did such a poor job that I had no choice but to go back to the one with the broken guard and just shave my beard off. Made me so mad I tossed it in the trash and came to write a review. Bottom line, if you *need* your beard, look elsewhere. This isn't the trimmer for you.
