Creative concept, but sort of an overkill solution for not that much of a problem.
Kind of funny he has gloves on while doing the actual oil change demonstration. If I have nitrile gloves on, I really don't care about a little oil.
I usually just grip the plug with a rag or whatever is convenient and don't worry about it. It's not enough of an issue for me to order a $20 tool. If this was a $1 special at Harbor Freight, I'd buy it, then probably use it once or twice.
Having been an oil changer in a shop before, I actually think this tool would slow me down in that setting.
The worst part of most oil changes is actually the filter. A tool to cleanly remove the filter without burns on a Chevy Traverse or Suzuki SX4 would get my attention!
