It's actually really quiet for a hair dryer I was shocked yes it's still loud but I was able to still talk and have a conversation with my husband while using it.  The smoothing brush is really all I used as the other tools are a pick and a straightener and I don't need either of them.  It dried my hair relatively fast especially because I only used the cold setting.  The attachments pop on and off really simply (not in a bad way).  The only thing I'll mention is the cord is pretty short if you don't have a plug right by a mirror like me it's a little bit of a hassle but other then that it's pretty great.
