Worth It
This does a good job at trimming.  The little vacuum bit collects most of the hair but if you're trimming a thicker beard, empty the little cup fairly frequently (and, no, it will not get ALL the hair).  The settings adjust quite easily and there is a wide range of adjustment.  The springy blade guard takes some getting used to.  It is rather large so getting it around can be a bit challenging; keeping the blade tight against the face while moving it to catch all the beard bits.  I find that cutting with the growth does not trim much but cutting against the growth cuts more than expected; at the same setting.  Against the growth does a better job of trimming, I think. It cleans up quite nicely.  I find the battery does not last as long as I expected.  I have to charge about every other use (but the, those uses are spaced a bit apart so the battery may just wear while it's idle).
