The installation of waste collectors are great. A really good invention, to save space and to store the garbage relatively odorless. The problem I find the installation. Here is an exact procedure needed. Once the screws are placed 0.5 cm too low or too high in the closet door, the system stops working. The garbage container remains eg. If it is too heavy hang when opening the door in the cabinet. Installation requires not only millimeter work, but also at least 4 hands. Alone this is not to deal with for a layman, despite artisanal experiences. Here must be found a simpler solution.
