content: If it wasn't for the really low price on this I would be very upset with the purchase. It's my first Delta tool and has left me disappointed. It is much louder than the other reviews indicate. Forget talking to anyone while it's on (in a small shop at least). It is also very top heavy and is extremely easy to tip. Hit one expansion joint in the concrete and down she goes. I'm trying to figure out a way to put it in the attic and run hoses because otherwise I can't see myself using this dust collector.
