The videos were fine. Not every video on youtube has to be professional, in fact I like seeing stuff of both kinds. As far as the tools go, I have the CXS and the T-18 and that's it. I very much would like that Centrotec Installers set, though I would prefer one with both SAE and metric sizes and both the brad point bits and the Zorbo bits, and so many other Festools. But I'm disabled and very broke, it took a long time to save up for what I have but I'm trying to build a place to live and I needed decent drill/drivers desperately. I have an older Dewalt 14.4V (American made) drill but the batteries had such a short life and I couldn’t afford to keep getting new batteries for it and the new Dewalts are made in slave labor countries like china and mexico so I was saving up for a long time for a Milwaukee, but about the time I had enough saved they also sold out to slavery. So I did the research and determined that Festool was the only power tool manufacturer who wasn’t using any slave labor and I got a CXS and I haven’t had any problems with it and I think it was a much wiser investment which should last far longer than any of the slave labor junk.
