Very good product -- easy to use! Battery somewhat short; but, I was aware of that  that prior to purchase.

This is a great product. Yes, the battery doesn't last as long as you'd like, but when do they? I would recommend this handy vacuum to anyone.
It is working well again and I was happy that Dyson came through and stood by their product. The woman I spoke with was very friendly and helpful.
