The order arrived promptly; everything is intact. Installation was a bit difficult because of the location of the mounting screws. The buttons are straight forward to use. Lights are very bright. Suction is strong, and so some noise is expected. The thing that they improve on is the cover of the vent adaptor. It's a flimsy piece of metal hung on two pins. When the machine is on, the metal rattles in the wind. Otherwise, so far so good.
