For less than a cup of coffee, I bought this splitter which plugged in and worked perfectly! Can't ask for more than that

I had an old telephone splitter that had stopped working, and I bought this new splitter for my 2 telephone connections and it arrived as expected. It was easy to install and I am quite pleased with its performance.
