Tire pressure monitoring systems

All things considered I called TST and asked them a slough of questions all of which were answered with what sounded like genuine concern for me, the customer. Now I am a hard sale, and I like my money to stay in my pocket, but most of the reviews (when you can find them) on any TPMS refer to TST. Most of said reviews, while they may have had a problem here and there, stated without fail that TST stood by their product and made every effort to fix or replace immediately. Even as far as to overnight parts to a CG. Well, that's enough for me. I will pay a bit extra for something who's company so evidently stands behind their product. The 6 piece 507 flow through system should arrive a my house Tuesday. I got 10% off too.
