Not Bad, Not Great
I've been using the shaver for a little over 3 months now.  It's very quiet, the charge lasts a couple of weeks, but the shaver takes 3 to 4 swipes over a 1-day growth stubble to fully cut it to a somewhat smooth level. The sideburn trimmer is useless - have to use a razor there.  Also have to use a razor for errant neck hairs.  All in all, not bad but not great.
