Review on Set of 4 Black Bolt-in Flush Mount Valve Stems by Circuit Performance by Terrence Castillo

What the hell! The filling stem does not screw into the valve. hats are on! But no, not a filler rod. And there should be 4 filling stems, one for each valve. I'm sitting here at a professional tire manufacturer and my tires are deflated because they can't fit a stem into a valve!
