Good video. I have the same gun and found much the same results. I always found that it doesn't really pull a joint together. I'm probably doing it wrong but for me it kind of introduced a 1/32 gap pretty consistently. FYI it's called a "senclamp" and it's still produced to today, unmodified as far as I can tell and goes for around $700. Mine lives in a very similar drawer and gets used occasionally because it's cool.
