Not Great
This Vonexx trimmer works, but not all that well.  The unit is fairly lightweight, with a lot of plastic in the construction, and it feels to be of average quality.  With the attachments on, it seems to do okay.  I trimmed my beard without any real issues using the 9mm attachment.  It doesn't snag and trims effectively.  The biggest problem is that it doesn't trim well without attachments.  When I use the trimmer alone (no attachments) to try to shape the edge of my beard and to clean up loose whiskers, it snags and doesn't cut cleanly.  It can't really get a good clean line around my beard with it.  Overall, for this reason,  it's not great and not recommended.
