They are made to the same good if not better quality than OEM/Schrader sensors. They got in touch with the CRP5011 TPMS tool very quickly and offered a replacement for only about $100 per sensor. I haven't tried programming with 3rd party TPMS tools but the launcher works fine. Would make them the sensor of choice in a full line tire shop. Valve stems appear to be interchangeable with most aftermarket brands of gauge stems. Highly recommended for value for money.
