Review on Schader Valve Self Seal Inner by Luis Adu

Received on time. However, it took me a long time to install it. They sent a new sight tube but it had a black cap on the valve. All others are green. Then the carving faded and there was dirt on it. The valve core was bad and would not inflate. Removed and overhauled with new valve core. The tire didn't fill up, just leaked. Took it off and found the valve stem had sheared off. Then there were 2 V-shaped cuts in the pipe. There's enough air in there to blow the green slime out of those cuts. Truth?
