I bought some "fairy lights" that contain about 300 LED lights on an 80 foot strip of thin copper wire. These were bought to attach the lights to the roof of my patio and they work great. Because they are clear, you have to really look to notice them. A few of them had trouble sticking, but overall, they work just fine and I'm happy with how they look and how they adhere to the aluminum and plastic of my patio roof. Tip: wipe the area where you intend to stick each one with a cloth saturated with isopropyl alcohol to ensure best adhesion.These were ok but didnt fully serve their purpose. They were easy enough to install but they also unstuck pretty easily, so I ended up removing them. I was trying to hold a cord down to the wall.Works well with lighting for my manager scene. Very satisfiedBought to use for installing Christmas lights on the bottom edge of my gutters. After cleaning the gutters for good adhesion with Alcohol most of the clips held OK and some fell right off. Also some of the clips broke when trying to get the small wires in the clips. Fortunately I had plenty of clips to get the job done.Adhesive did not work well on satin finished walls! Even though I cleaned and resurfaced them slightly!I bought these to hide my dash cam wiring. So far, so good. They work great, and are small enough to hide the wiring up at the top of my windshield on the underside of the headliner.Does the job and nice to not have to nail the walls!Our only conn is that some pieces didn’t have the same strong adhesion as the other pieces and tend to be a bit snug fit and not easy to get the Ethernet cable in the groove. With some persistence we made it work.The clips are nice. Perfect for Christmas lights and thin cords. They are small and unobtrusive and so far the adhesive is holding up well. The only problem for me was that the red backing was such a pain to peel off that I actually had to use "sailor's words" to ventMe sirvieron para cambiar las cintas que habia puesto en el cableado hacia algunas camaras de vigilancia, cables de red a laptops y etc. pero. les falta adherencia. quiza tenga que ver con el tipo de pared, pero en algunas, que son como de acrilico o asi como plastificadas, se quitan facilmente. cuesta trabajo quitar la hojita roja que protege la parte adhesiva. fuera de eso, no encontre problemaFuncionan y cumplen su propósito, el problema es que algunos de los clips se despegan muy fácil y no soportan ni el sostener una parte de un cableEs muy bueno en interiores, un poco menos en exteriores.Pegamento muy malo y se sienten muy débiles las pestañas de sujeción.Cumplen con su propósito
