I was all ready to jump down the installers throat until I saw that folding chair. Hell, the installer probably figured the guy didn't mind ugly w/ that ratty folding chair at the desk at the end of the video.
Seriously, I'm not defending the installer, but he did ask for an apartment install. Sometimes one can't fish through the walls of a leased multi-dwelling unit.
He did a good bit of work in a hour though. I'll give the installer that much credit.
