I have had the System Diatech for a while now and I yet to have a problem with it. I love it cuz its out of the way and you dont have to buy any special cables to use it. parts are easy to find for it and its smooth as hell. plus you never have to adjust it like rormal rotars so it stops making that "Clunk" sound everytime you turn your bars, from the tension on either side being off. It's a great product!
