This seems to be a solid product. It worked pretty well, although I had to repeatedly tighten the two set-screws that hold the snake into the clutch. When I really leaned into them, they finally stayed tight.
Unfortunately, the snake wasn't quite long enough for the job. I had to rent a 1/2", 50 foot power snake to finish it.
