This cell phone jammer was a perfect replacement. It works as long as you put the fobs in the metallic area. Its easy to miss that at first. But once you get the hang of it, it is simple and seems effective. I've tested it a couple times. This product is great. It's thin. It sticks on. It removes easily and goes back on easily. I can use them on all my devices’ webcams because the material is transferable. The Carbon color blends well with all of them
