Query: Beware!

I agree many of the other reviewers -- this product is dangerously loud! I frequently attend concerts and like my music louder than anyone I know and still find this product painfully loud -- so much that my ears ring for hours after use. Aside from this, this vacuum only sucks things up in the 2-3 inches straight down the center of its path. Sweeping along the edge of a wall is useless unless you approach the wall perpendicularly, going back and forth incrementally down the length of the wall. A piece of junk. It gets 1 star for not breaking during the 11 months that I used it.
