I bought them because of the advertised 3M adhesive, which in my experience has met my expectations for various applications. I used these in a CCTV install job to hang cable on freshly installed painted and unpainted drywall, concrete, cinder block, plastic, and metal. As long as the surface was free of dust, I got good adhesion. In fact, I was able to tighten and cut the cables using the maximum force setting on my zip tie installation tool without waiting the suggested one day between…

Product clearly showed 100 PCs and zip ties. Doesn’t have any zip ties with product. Misleading. There was the correct amount of pieces though

I was using the command clips for cords and velcro command strips for power bricks, but I find these to have better adhesion for the power bricks(and gravity) and better flexibility when I needed to make adjustments. Three squares did lose grip but I fault this to my installation. I replaced these three and haven't had an issue since. I highly recommend these!
