Hello on 10-14-2013 (john Ziegler was our service manager). We had Criswell Chevrolet dealer in (503 Quince Orchard Road, Gaithersburg, MD, 20878) installed the Primus™ IQ brake controller made by tekonsha. They charged us $274.24 for one brake controller. We called tekonsha and spoke to Andrea and she told us that the Primus™ IQ. PN 90160 retails for 107.91. We are writing this review to let Criswell Chevrolet dealer in (503 Quince Orchard Road, Gaithersburg, MD, 20878) that they ripped us off by selling the Primus™ IQ. PN 90160 to us at 166.33 over retail price.\r
