Dyson Hair Dryer HD03 Although not every time, sometimes it would stop working after about 3 minutes of use. There were also times when it didn't stop for over 10 minutes, but this is a junk item, so please refrain from purchasing if you are at all concerned. The sound changes, but the airflow doesn't decrease, and you can dry your hair with strong airflow. Even if it suddenly stops during use, you can turn it off and then on again to use it. The main body has scratches on the handle, paint peeling around the edges, and signs of use on the wiring.
