Definitely seems like a gimmick. The headline will be "This NEW Innovation Will COMPLETELY Change How You Turn Bowls, ELIMINATE Mistakes."
Unfortunately, some folks who are trying to get into turning for the first time will fall for it because they don't know any better.
The one guy claims when you turn a bowl, you always plan to take a little off the outside after you flip the bowl. However, most of the bowl turners I've watched on YouTube and those I've seen do demonstrations at SWAT completely finish (sand and add a finish) the outside of the bowl and never touch it again once it's flipped around. My own experience has been the same, and I'm by no means an expert bowl turner.
In fact, for any bowl with non-vertical sides (and even smaller bowls with them), it's a bad practice to turn the outside once you've attached it to the chuck and flipped it. There's way too much opportunity to run your tool or hand into the jaws of the chuck while the lathe is on. At best, that means an early return to your sharpening system, and at worst ruined tools, deep lacerations, broken bones, or severed fingers.
When I've had issues, it's been due to the bowl not being stable on the woodworm screw, resulting in the blank moving on the chuck while turning. If you don't fix that before you flip the bowl and attach the chuck, then of course you'll have to fix it after, but that could be just as bad a problem on this new lathe. The solution isn't needed if you properly mount your blank in the first place, and won't fix the problem if you don't.
