Review title is 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 didn't 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 whoopie.<br /><br />Well, 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 5 to a 4.  I liked the 4 better anyway, so stuck with that.  I happily trimmed to a 4 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 1 when I was in the middle of shaving!  I went from a nice beard to the 5 o-clock shadow look!  I AM FURIOUS!<br /><br />There 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 it!<br /><br />Until they build this with a locking device, avoid it, or you could lose your hard-earned beard- just like I did!
