I bought TST 507 system and used it for the first time on our recent 2 week trip. It worked great and gave me peace of mind while driving. I did get 3 alarms...the beeper goes off and the affected tire flashes the temperature and pressure. Each alarm showed something like 320* but normal pressure. I pinged this forum group with a question about "phantom alarms" and the most likely culprit in my case is that I have an atomic clock sensor mounted in both propane closets (one clock is in the front bath and the other is in the living room). The alarms are scary at first - but when I saw the ridiculous temperature flashing I silenced the alarm. For the first one I turned the monitor off and on and it came back with normal readings. For the last two I just silenced the alarm and after a few minutes it resumed normal readings.

Like DQDick stated - I think I will be able to use this system for many years. I think it is well worth the cost.
