Good quality. I was looking for a "quick fill" solution for large 22.5" commercial tires. It's better than what I had, but there are two things to note: 1. I assumed it would be a 1/2" or at least a 3/8" air hose since it's considered "big". Diameter" is marked. That's not the case. The hose has an inner diameter of 1/4 inch. It's probably still not the smallest "throat down" point, but after switching to 1/2" air line it was a bit disappointing to see all the high flow air drums and fittings in the Milton "V" style high flow gives line is used here. 2. The tail is NOT suitable for normal valve stems. It will not fit your car or truck tires or even commercial truck tires. My guess is that they are made for large SUV or tractor tires that use a custom valve stem, so if like me you're looking for a quick-fill solution for 22.5" tires, you'll have to buy and swap the other end of the inflator.
