Review on TST 507 Tire Monitoring System: 4 Sensor with Color Display - Perfect for Tracking Multiple Trailers by Zack Frazier

Fast and easy setup: It literally took less than 10 minutes to remove existing valve stem caps and install inspected caps. Comes with a lock nut that attaches to the back of the monitor to prevent theft. The kit comes with a repeater, but so far I haven't had to use it. The trailer is 31 feet long, the pickup is about 19 feet long and reception has been flawless so far. It takes about 5 minutes to sync a Caps monitor. So don't expect it to be ready to use right away. I turn it on, then start plugging in the trailer and getting ready for the trip. When I'm done with my ride, it's synced and ready to ride. Great product, the security it offers is worth the money!
