*Update 2 1/2 weeks later (August 10, 2018):
I'm more than pleased with this new Powermatic III. After rolling 500 smokes, there hasn't been one mishap or bad filling. I know in this video it sounds like it takes a long time for it spit one out, but when sitting down and feeding one tube after another, without the need for pushing down the tobacco and tapping it in, it's actually faster with the new Powermatic III, at least in my experience. I've also found that the Golden Harvest tubes slide on easier than the Zens.
Original video comment July 25th, 2018:
Yes, dear ones, I know how dangerous smoking is - I've been doing it for over 50 years now. This is just for those folks who do smoke and try to save money by rolling-their-own.
Powermatic III has a digital counter display, is auto filling and compressing, has a density adjustment and a 1 year warranty. Currently (July 2018) it's pretty expensive at around 200 dollars. The Powermatic III is being advertised as only for shorter King tubes but it worked just fine filling my Zen 100's. Actually, I've tried it using regular King tubes and it's quite messy, leaving a large chunk at the end, but this machine fills up the 100's from filter to tip, consistently. I'm quite happy with it.
My older Powermatic II is still running strong after 8 years now - it's the best machine out of quite a few I've tried.
