Review on TST Tire Pressure Sensor Tow Car Pack: Enhance Performance with TST 507 Systems by Brandon Pratt

use this on my toad. They all worked great with my existing TST monitor. The anti-theft device has been removed to make it smaller (I remove it when in doubt and when the trip is over). Also, I don't program them in any particular way in terms of location. All I want is a warning if any tire goes flat ANYWHERE on my van and my toad. No matter which ones (planning to stop and see everything asap for ANY monitor warning. I have them on rubber valve stems (quite short) on my Kia Soul. So far (2000 miles) no problem. Knock wood. Don't want to fit any of Metal valve stems.
