We've had our TST 507 flow through for almost five years, and when I ordered it, I also ordered the repeater, and never regretted it, as it always has worked flawlessly. A little over three weeks ago, we were traveling south towards Sun City, and got the alarm. Turned out it was a valve stem that had come loose, and gave us plenty of time to safely get off the road. Would not want to run without the 507.
