Easy to use
Style: 6-Speaker
This was a lifesaver. After buying a house, I discovered a huge mess of audio cables wired throughout the place, and this plate made it possible to finally get everything organized.
Quality is decent, not the best, but good for the value.
Super easy to use and connect even old wires to it from the back.

These wall plates look good and work well
Style: 2-Speaker
I used these wall plates for my home theater system. They are easy to install, look good, and accepted my banana plugs perfectly. They make my installation look tidy and I am pleased with the outcome. I have used other Cable Matters products in past and have always been happy with the results.

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.
