The length is sufficient for the usual places behind the sofa, but also behind an open cabinet, without that it looks ugly. It can also shorten or lengthen as required with further. The cable channel than enough for example for two good speaker cable and is highly compact and makes the wall a very good impression, you can "disguise" it as a good room decoration.
Opening the lid, which is very stable, is easily and holds after closing remains very good.
This also applies to the double-sided adhesive tape which holds a woodchip wallpaper immediately and well. One should therefore really paying attention to that previously found the optimal position before decreasing the protective film, because you can no longer so easily removed again.
I would recommend the product and the supplier at any time.
