I fell for that one...I've tried it numerous times, and have YET to get it to work. that was 20 bucks wasted.
only thing I've gotten to work is a thing called an "e-z-out". (I think). you drill a small hole into the center of said screw, then use the gizmo, which is a tapered "bit" with left-hand thread. it fits into a hand-held "chuck", with a lever handle. as you turn it into the hole, (to the left), it grabs and wedges itself in there tighter and tighter, until it can't turn any more, at which point it starts working on the screw.
The other method I've used with good success is to cut a big slot into the screw head w/ a dremel and a cutoff wheel, and use a big screw driver. but if that doesn't work, (sometimes the head will snap, or you just can't get enough leverage), I go w/ the ez-out.
