We use EEZ tire system and love it. Before we had one a tire got low on our towed car. The tire came off and it was a delay. We put these on. We needed the booster, it tells you temp, pressure and has a low pressure, high pressure alarm along with a rapid deflate alarm. Our last trip a valve stem went bad and we had a slow leak. Alarm went off, we put more air in got to our location all was well. The tire and wheel replacement on our SUV was more than the system cost.
