Yes, it's plastic, yes, it's a bummer, but is it?
I use those in the studio, away from gig-threats, but the plastic is quite thick and feels very reassuring,
the parts fit peeeerfectly, the soldering points are rugged and not too bendable, generally the quality is strong in this one.
The only reason for 4/5 stars on "Total" is that I wouldn't trust those for live use without having a backup cable just in case.
