Excellent, clean look
Style: 1-Speaker
Great wall plate for that clean, in wall wiring look. Easy to install and connections are solid.

Great...but could be a bit better
Style: 2-Speaker
Almost perfect. Easy to screw apart and insert wires to both the back and to the front, or do what I did and screw the wire onto the back and then use a banana plug for the front. My only complaints are that the back piece sits off the wall a little, so the plate doesn't fit flat and tight against the wall. It leave a little gap around the edges. The other complaint is that the back piece has some flex in it, which makes me nervous when I push plugs into and out of it. I think it probably will hold up fine, but it feels a little oogy to push banana plugs into it and see it flex. Comes with all the hardware needed. Just need a philips screwdriver and wire cutters and you're good to go. Super easy to use, and way better than the spring loaded connections it replaced.

Really good wall plates
Style: 1-Speaker
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.
