Query: Windtunnel stinks!

My husband and I purchased this machine less than two years ago and have been totally dissatisfied w/ it! It is heavy, awkward - generally poorly designed. It is top heavy and tends to tip over easily when using the attachments. The attachments are difficult to connect and access. I honestly could not recommend this to my worst enemy. Everyone who uses it expresses the same. When I filed a complaint with Hoover and the Hoover store where I purchased it, all they could say was "sorry". I did not complain until six months ago since I thought perhaps I just needed to get used to it. Hope this is useful in another person's search for a quality vacuum!
