These simple switches will make life much more convenient when using devices that use a coaxial connection. They last a very long time, especially when the connections on the primary side are configured to toggle without the need for an actual antenna/cable switch on the switch. For example, if you're switching between cable and satellite, set the input on the TV to both, and you don't have to flip the physical switch on the real switch. Over time, the physical switch can loosen with use, requiring quite a bit of tapping to get the best connection. Hey, just exchange and be happy. The little effort is worth it.
