Five-Tire Pressure Equalizer System with Lock on Chucks

This tire pressure equalizer works great- now. Was missing parts from the factory. Had to call and get missing parts shipped to me. Customer service was very good and prompt. Makes airing up tires easy and allows us to be more productive since you can set the machine to your preferred pressures and continue working on other things. Would have given it 5 stars if all the parts would have been in the box.
