I've had this stored in the closet since I no longer needed it. It shows signs of use, but there are no particular problems. The set includes the main unit, a waterproof sheet, a drain hose, an apron, a hand pump, two dedicated bottles, and a pillow. Although there is no air release plug, it can be exhausted using the round air pump in the last photo, so there is no problem with use. There is no original box or instruction manual.
