The brush falls off here and there....I guess they don't make the brush more secure so you can take it off and clean what hair may get under it, but it is annoying when it happens, though not very often. The results of this blow dryer are worth it. Just be careful the brush gets very hot, and if you try to put it back on immediately, it is very hot. I have wavy to curly hair, and I love how I can use this to straighten my hair and still have body to it. In the pix I had just dried my hair...took about three to four minutes..and then I ran a straight iron over it for about thirty seconds on the spots on my hair that have flyaways. I got the shampoo at Walmart too..Garnier Whole Blends, which I highly recommend. It makes my hair look so much healthier and smoother. I used the honey one, but I also use the apple one, and the argan oil/cranberry one, and I plan on buying the other ones they have too..they are amazing!
