Pressure Pro VS TST

I've run the TST507 system with flow-through sensors since early 2014 with no problems. My rig does need the trailer repeater as I proved when I forgot to plug it in at the rear of the truck one trip and got a lost signal alarm on 1 trailer tire within 20 miles of the campground and the 2nd about 15 miles later. I guess the requirement for the repeater depends on distance from the trailer wheels to the receiver, placement of the receiver, etc. I bought the repeater with the system just to be sure, and sure enough, I need it. I'm happy with the system and its performance - it's triggered high pressure alarms on a couple of trailer tires (I had the alarm set point adjusted too low) that were aired up at 35 degF ambient when we were towing at 85 degF ambient temperatures and 100-105 degF tire temperatures.
