This product does exactly what it says. I just wish the center wire clips were designed a bit differently. With my cat3 telephone cables I connected, the thinness of the cables means that the center clips don't offer much resistance. This lets them come free from the center clips when running new wiring through it. The 110 connectors would hold the wire in place so it didn't come loose from the DD1C, just the center clips. Overall, this is exactly what I was looking for and I it was the right price.
