These plates came on time, packaged well and are "doing the trick". The plates, while fairly light-weight are perfect for my new system. They installed into the junction boxes very easily, hold the wires snugly and the banana plugs are perfect for my usage. If you need a nice, easy to install, good quality, wall plate, I would highly recommend these.
