BAD Design, Unusable Trimmer [SEP] When my (non-vacuuming) Norelco trimmer would no longer take a charge, I ordered this item, not too concerned over whether the vacuum was effective or not.<br /><br />What I received was a poorly designed trimmer:<br /><br />1. To hold the trimmer, one must place one's hands over the vacuum air exit slots, thus throttling the vacuum.<br /><br />2. The guard was so complex to attach and detach that it took 10 minutes each time to do it.<br /><br />3.  The closeness settings don't actually lock in, and tend to "wander" toward (1), the closest setting.  And so I would find myself completing my trim with 3/4" length hair on one side of my face, graduating to stubble on the other.<br /><br />I finally threw the thing in the garbage after a week and bought a leftover non-vacuum Norelco model like the one I previously had - $19.99.<br /><br />So, if you see some poor soul walking down the street with long whiskers on one side of his face, and a 5 o'clock shadow on the other, be kind.  He's probably not dimented - just the victim of this "new and improved" beard trimmer.
