Brian- They did indeed force a blast of dust back up through the bag. If you were to take a "full" type C bag, leave it attached and cut the top off you will see the hole in the center. I dont think it caused any or much "pre mature" death it just cut the suction efficentcy.
Pete & Morgan- thanks for sharing the photos I like the unique bottom cover to keep the suction concentrated to the hose. I also love the chrome version.
