The quality of the valve was superb but it did not fit exactly for my specific requirement. This was not the error of PCPTunes but rather my own error. My first thought was that I was stuck with a product that I couldn't use. One email and a very quick response later my problem was solved. I cannot express just how much of a relief it was to have the level of support that I received from the Sales Team. The response, the solution, and the replacement was fast. When doing any business over the internet, the great unknown is trust. As far as these guys go, you will get a superior product at a competitive price and they stand behind what they offer. I will post a follow-up review once I've had time to quantify results. „
