I bought one of these about a year ago and I love it. Got this one on first use when I pulled it back to press against the stem the head broke. Air blew everywhere, I winced and pulled back, the hose whipping for a minute before I got it under control. It looks like the steps were cut too deep when they were cut, or the brass tubing was too thin. I used my first dozen times on my outside wheels on an RV where the bars were facing in. I think it might just be a coincidence if the product didn't change specs.
