I bought two. Very nice, very good construction overall EXCEPT for the magnets which are not strong at all, resulting in the cables falling with the slightest touch. Thus, they cancel out its main function. I wouldn't buy it again.

The magnet does not hold its weight. I'm not even discussing if it holds when you put a cable inside. Neither in a horizontal position nor in a vertical one. It doesn't work, so it's not suitable for the job you buy it for. I don't know if I came across a defective one, but I see other negative comments as well. I will probably get a system without a magnet but with adhesive.
0/5 from me...

The magnets that attach to the cable are very good and strong. However, the base is useless. I have metal shelves, so they worked very well for me because they attach directly to them, without needing the base.

It is not functional, the magnet does not hold and the cables keep falling down constantly. I bought it for my office to organize the cables, but it is terrible. It is not worth buying
