I bought this to go with the Mr. Nozzle 115-DB kit and it works great.  I mean, it's just a hose, but it's not flimsy and doesn't collapse like the cheapie that came with my Craftsman wall mounted vac.  Now with the 15 footer that came in the Mr. Nozzle 115-DB kit, and this 12 footer, I can roam around 27 ft. of my garage sucking up anything in my path, and I don't notice a bit of drop in suction at 27 ft. vs. 15 ft.  I love the convenience of my wall mounted vac and 27 ft. of hose.  I'm giving my "lug-along" ShopVac to my brother-in-law.
