While I enjoy the benefits of having a diffuser-type of blow dryer, I was disappointed in the ease of operation of the straightening/anti-frizz attachment. It's pretty cumbersome and I'm not sure it is any better than just using a round, alumnimum-based brush. In fact, if you are already using a round brush to take the frizz out of your hair I would recommend that you stick to that method. This type of attachment was just too difficult and ineffective for me to use.I still enjoy the quality of Conair's products but I am sorry I spent the extra bucks for this one. I could have purchased a much-cheaper Conair dryer with a simple diffuser.
