The product works: I have two pairs of 12 AWG speaker cables and a Cat 5 Ethernet cable running around five corners. It hides them well and the housing blends in nicelyTwo things you might want to look out for:(1) The adhesive -- VERY sticky. A good thing. But if you set it in the wrong place, don't expect to be able to reset it without providing your own glue (and tidying up the mess it leaves behind the first time)(2) The "joints" work very well IF you don't set an edge of the housing flush against the skirting board/wall/ceiling: they need a little extra wiggle room and if you apply the housing too close, they won't click into place.
