I have both a Dyson Fan and Vacuum. Both seem to be great products so far after a little over a year. Overpriced in my opinion, but in the end really good products. the fan both cools and heats our kitchen area quite well. The vacuum charge doesn't last more than about 20 minutes, we didn't buy the higher end one, it is still good for what we need. we don't use it for the entire house by any means. It is primarily for the kitchen and hallways and furniture. Having a large dog that sheds like crazy this has been a very handy tool to keep the hairballs under control. I do feel Dyson could lower their prices, that would be my only complaint.
