Took it for a test drive yesterday. Worked great. Surprisingly quiet. Only complaint is that the hose, including the metal nozzle extension, is about 4 inches too short. The canister wanted to tip on its side when I was reaching in from the top and trying to get into the back of the firebox. But, it's very light, so holding it by the handle while vacuuming out the KK was no big deal. I could have used one of the plastic hose extensions, too, which would have been plenty of slack. Will likely go that route next time.
