You don't need to be a rocket scientist or tire expert to install this system. The monitor is digital and you put a sensor on each tire. It's outside, not inside. It's easy to connect and use and works great. You always know how much air is in each tire which is great for me as my husband is very fond of tires and we seem to go through more than most people. It's great for yourself or even as a gift. Would definitely recommend with teenagers in the house as you can never be too careful.
