I'm very impressed with the product.  It's very quiet even at high fan speeds and when used for heat, warmth is dissipated evenly in a room. There is less need to crank the central heat on since the Dyson does the job quite efficiently.  The remote control has a magnet that allows the device to be attached to the Dyson and let me tell you, as someone who loses remote controllers quite often, this is just an awesome idea.  With regards to it's ability as an air purifier, I would say that it does the job well.  I noticed a decrease with dust along the entertainment center where the Dyson is located.  Looking forward to warmer weather when I can use to Dyson to cool me down.
