I have been using the Valor TPMS and my unit is dead. I have a recently installed set of sensors that I don’t want to scrap so I need to replace the monitor. The US rep for this company retired. I’ve been trying for a couple of months to get a call back from his replacement. I’ve talked to the company HQ and they can’t help. They just keep giving me names and phone numbers of other sales people that don’t call back. Does anyone know if there is a US retailer for these units? Does anyone have a unit that they aren’t using that they would be willing to sell? Any suggestions would be appreciated.
