Already own 2 Speedhut gauges and they work well, the product is good. Unfortunately for me, I was geared up to buy a set of 5 additional gauges during the current labor day sale, but what the promotion fails to disclose is that the 15% sale nullifies the 10% multi-gauge discount which is in place all year long.... so this "15%" sale is really only a 5% discount from normal.
