VisioRx says,

John did an excellent job in a rather diverse project. He was very helpful in finding a nice voice for our videos and he then went more than the extra mile in editing the videos and making sure it all turned out perfect. The fact that it turned out we had made some errors in the materials provided did not upset John, and he worked diligently to correct our mistakes. A top-notch freelancer whom we can highly recommend.
