great until the setting slips [SEP] i scoured the net looking for the perfect beard trimmer to trim my beard that i brough back from iraq i did not want to look like a terrorist so i needed a trimmer to keep my beard looking civilized i read the reviews here and was prepared for a somewhat weak vacuum even on turbo no big deal i wanted results and the vacuum was just a perk anyway it caught maybe half the hair on turbo so whoopiewell i should have paid more attention to the negative reviews i was careful not to hold the trimmer by the click wheel to avoid accidentally going down a setting i did that once and clicked from a to a i liked the better anyway so stuck with that i happily trimmed to a once a week sometimes twice to clean it up for the last couple months and it worked well until just a couple of days ago when the setting slipped all the way down to when i was in the middle of shaving i went from a nice beard to the o clock shadow look i am furiousthere needs to be some sort of setting lock that prevents it from just slipping and ruining your beard how hard would that be just build the dial with a notch you can slide a bar into in order to lock ituntil they build this with a locking device avoid it or you could lose your hard earned beard just like i did
