Thanks to my knowledge gained in practice, I’ve noticed that the Hummer Logo Black Tire Valve is a typical case of an automotive accessory that looks good only online. The valve stem was made of low-quality material that bent even on the slightest pressure, making it useless after a few weeks of installation .The only pro was that it looked stylish initially but it didn't last long. In conclusion, don`t waste time or money on this product..
