I didn't use this piece of junk until I had too much time to return it to say its junk really stretches it, it absolutely is, take 25 Dollar and give it to the bum on the corner, but at least he gets some liquor from the deal. If only it had taken me 5 minutes to drill through the side of my van. The resulting hole was neither round nor precise to describe rapid impact cutting. I think China forced me to do it.
