I also purchased the Dyson less than two weeks ago as a gift to myself from Sephora with a store coupon. Before purchasing, I asked 2 employees if it was returnable if I wasn’t happy and was told that wouldn’t be a problem at all. It is much lighter and easier to hold than my old Sedu dryer and I agree with Maya54 that it is faster, perhaps cutting down the time by a 1/3.
While it isn’t as loud as a typical blow dryer, it still noisy with a higher pitch sound that my dog isn’t crazy about. At first I was concerned because I thought it wasn’t straightening my curls out as well, so I dried one side with the Dyson and the other with my Sedu and compared. My daughter thought the Dyson side was slightly better and I couldn’t tell the difference. End of story… I’m keeping it. Mostly because I feel like it has shortened the time I stand in front of the mirror.
