I Agree, but when on the road, or better, when off the road, the buddy is the best choice.

Imagine off roading, down a trail, or on the way to work, etc, you're not gonna have your laptop with you all the time, but this little EAS Buddy sits right in the glove box, smaller then a cell phone and it will get you home.

 

The Buddy box, and if your looking for a cheap fix and your compressor is going try the MARS system. That being said these are band aids for the real problem system leaks. I too have no affiliation with either of these guys. They are just like us trying to make our trucks last a good long time.
