yes used a few times and broke my neck when i checked the pressure on the inner tire. heavy trucks? Do not make me laugh. I didn't even pull that hard so I'm guessing the failure was stress related. Why put a metal collar on cheap plastic and claim superpower. As you can see, the white on the black plastic tells us that it has deformed under tension and that it is cheap toy plastic. not abs. no polypropylene. You should know that trucks drive on different roads and most of them lose their valve covers. I'll admit that a mud-filled valve requires more care in measuring the pressure by rocking an air chuck over the stem until it seats. The standard piston and cylinder gauge you all know and love is metal, and for good reason. no inferior plastic. Don't be fooled by the lies, it's a toy made from toy ingredients
