Gentlemen,
This thread is wandering off the point, and is not a comparison site for various makes of chuck..
The thread was posted to warn that a safety issue exists with a product that has been supplied.
Ketan is to be praised for his honesty, and responsibility, in making public this problem, issuing a recall; and in initiating investigation and recovery, back up the supply chain, which may affect this item if retailed elsewhere.
As already said, FULL MARKS TO KETAN for this!
Howard
