Ordered this with some trepidation as it was my first “big” Groupon order. It came in just a matter of days. Some reviewers mentioned their units didn’t work on arrival, but mine snapped together fast (Dyson veteran here), and was running smoothly in just 5 minutes. My 15-year-old DC17 Animal was a goner, bad clutch and all. It was a relief to have this lighter version purring like a big cat.
