First, it is refurbished with a 6 month warranty. But...These go for over $400 new! Now $219.99 for today only. I have a Dyson fan which I love to death because its so quiet, and efficient, and adjusts low super low. This one is a fan, witha heater function.
I have a Dyson handheld vacuum, and it is easily the best handheld vacuum I've ever used. No, the battery life isn't going to let you vacuum an entire room, but if you were going to vacuum an entire room you'd get a large vacuum for the job.
Mine is perfect for the quick vacuum jobs such as the inadvertent spill of ground coffee, or the regular car vacuuming when I have passengers.
