My company has used Milton products for many years. So when we needed to replace our inflator that was over 10 years old, we went with Milton. We received two faulty inflators. They let air out of the valve and do not inflate the tire. I called Milton support. Carlos told me that the small ball inside could come loose, causing air leaks and malfunctions. These inflators were brand new, straight out of the box. That's not the Milton company I remember. I'm happy for AMAZON with their right of return, otherwise I would be left with this rubbish.
