Figured I'd give a quick update: just did a 1000 mile trip from PA to FL (and 1000 back,) and the TST TPMS worked flawlessly. This was my first trip with them, and nothing like a baptism of fire with a 2000 mile haul to really see if they hold up. It was really interesting to see how the pressure went up (to a degree) as the tire warmed, and to see the temps fluctuating from the sunny to shaded side, day vs night, north vs south, etc. I'm very happy with the system. Hope you get your valve stem issue ironed out!
