I ordered the refurbished machine from Overstock who delivered it promptly. I have read many negative posts about Dyson Customer Service on other sites, and that you must immediately register the refurbished model with them to have the six month warranty. When I went online to Dyson's site to register my vacuum, the site said my serial number was invalid. I tried to call them three different times, and finally stayed online for over an hour to speak with customer support. I gave him the serial number and he supposedly registered it, but I have no documentation. The vacuum looks like new, but the manual wasn't very good at describing how to assemble the unit, and it took me awhile to find the serial number (located behind the plastic bin). 5 Stars for Overstock, but I took a star off due to my Dyson experience.
