My system works okay so far but I understand that the TPM valve stems are pricey.
About $120 per stem on the TPMS sensors. Of course that can vary from vendor to vendor. SOWARDCUSTOMS quoted $101.60 on his thread with 20% off, if he is still doing that, it looks like he is. page 2 post #40

Was 25 degrees here this morning and mine came on, no surprise though, not when it drops this cold all of a sudden.
