dislike the fact i can only use on tips of hair or it tangles [SEP] this is a heavy an awkward unit to use if i try to dry from or near base of scalp it will tangle in my hair it will only work when using just on the last inch or so of my hair i am not happy with this item at all my other complaint is bigger in diameter than stated yes the center of brush may be inches over all is so both the small and large brush attachment is larger than i want
