I could not use the product because of marriage. I'm only writing this because I just started using it. Bought March 2020. I installed a compressor adapter on it and then connected it to my 150psi compressor hose in the tank. When I pressed it onto my tire's valve stem, I noticed that no air was getting into my tire. I removed it from the valve stem and then put it back on the tire. There's still no air. I looked at the pin at the end of the product, the pin didn't even stick out and was very loose. I would not recommend this product to anyone.
