TST Tire Pressure Monitor System - Interim Update

I bought a set last year with the flow-through sensors. Worked great, except the length of the longer sensor combined with the angle of the valve stem (metal) allowed them to project beyond the sidewall of the tire! I actually busted up one when I scrubbed a curb at a dump station, so I contacted TST who exchanged them for the "old style" button sensors - even the damaged one - at no charge. Now they tuck in nicely & are well-protected! Just sayin...
