Bought this after consistently seeing postings on RV websites about RV body damage caused by blowouts. Had new tires put on 2 weeks ago and installed the sensors. As we were starting our trip I noticed left rear tire was losing pressure fairly quickly. Detoured to tire dealer who discovered that rim had not been properly cleaned and new tire bead did not seat properly! Without TST this tire would have gone flat and most likely the front axle tire on my fifth wheel would have blown under the unequal load. Very satisfied customer.
***Urgent Update** 2nd half of our trip saw another leak in a different tire. Back to the dealer. They had inadvertently installed the wrong valve stems! Rubber vs. all metal. The rubber stems were chafing where they passed through the rim because of the extra weight of the sensor. Sounded bogus, but a close exam of the stems proved they were right. They replaced all 4 stems with 100% metal stems - just like the TST instructions call for - and all seems to be well. Coincidentally on our return trip home we had seen a travel trailer by the side of the road with a blow out and body panel damage! Was grateful it wasn't us.

Takes a while to refresh.

Customer service was great. I knew immediately when I started having a tire problem and was able to prevent major damage to my RV. Paid for itself on this one trip.

Easy to use and read. I installed myself without having to call my son. The tire pressures will register without moving the trailer. You can add or release air from the tires without removing the sensors.

This gives me peace of mind while pulling our 5th wheel travel trailer. We're new to this camping thing, but getting into it.
