Reviews apparently lie.
After reading many reviews of this product I was sold and went ahead and ordered it.  My mistake.  The unit is apparently not designed for heavy, thick or long beard hair, as it does not trim that well, the vacuum just clogs up and then blades tend to pull rather than cut smoothly.  The blade guard (?) just lets hair jam up against the blades, which again makes for a less comfortable trim.  My plan is to now get a much simpler version of this type trimmer and go back to trimming as I have always done it.
