Bulky
As a one piece item it is both bulky and awkward. Because of its size, it is difficult to position in the way that is most beneficial for cleaning your teeth. It is virtually unusable for a child or a frail person. The controls are difficult to use since you can't see them while using. If you want to change the pressure you either experiment and let it go from dribble to fire hose in an instant or risk it shooting across the room if you look at the controls while using it.  Not a well designed product.
