The power strips do what they should. Taking into the instructions for use and cleans the surface of the bonding surfaces, hold the power strips the subject. Of course limits the power strips (natural) are set what I want and fix how heavy the object. The power strips can be removed without leaving residue. Ideally suited for use in the home and to avoid holes in the wall.
The price / performance ratio is okay. Elsewhere you do not get the power strips also necessarily cheaper.
