The holder is stylish and works, provided it is mounted on a smooth surface. I wanted to mount it directly on the plastered wall. In this case, however, stuck the capsules and does not slip when the bottom is removed. This is described in the enclosed instructions, but not in the online product description. Therefore only 4 stars The remedy: Just 30 x stick to a frameless picture holder 40 cm and hang on the wall! The background = the image in Picture Frame you can customize at will, eg with aluminum foil.
