As per my post last week, I bought a Dyson fan to see how it was in person. I was pleased to hear that it wasn't as loud as some reviews made it out to be. Even at its highest setting, in our large bedroom, I didn't think it was a problem.
It also put out a decent amount of heat; our room gained about a degree every 6 minutes in my extremely simple test. And it is built to the usual Dyson levels of fit and finish. It oscillates like butter and the whole thing is silky to the touch.
This one is the grey and blue model (although the box said white, strangely enough). I still think I'll get a white one as we will be using it in the white kitchen area. Overall a successful test and I am edging closer to purchase.
