It works well enough, though I wish I had noticed that the concentrator nozzle just slides on before I bought it. I've been using this hair dryer for about 6 months, and the nozzle has started to randomly fall off when I'm using it. I wish I had gotten a dryer with a nozzle that snaps on instead. The dryer itself if decent. It dries my hair relatively quickly, but the heat settings seem a bit off compared to other hair dryers I've used. The warm setting isn't very warm, so I end up using hot most of the time so drying doesn't take as long.
