I have a slow tire leak. Being in quarantine I want to go out and pump up the tire at least every two weeks because of the slow leak. Then it snowed in Texas, so I couldn't catch my breath at the gas station as usual. My tire is completely flat. poof So I turned to Revain for help and came across this article. Received last night. I followed very simple instructions this morning and am now ready to go for a few more weeks. HOORAY! Love how quick and easy it was - full to full in about six minutes (45 psi). Now it's safely tucked away in the trunk of my car in a nice bag it rode in, until next time. It's a lot smaller than I expected. And the looming pressure in the back of my mind to find time to catch my breath at the gas station before it was too late vanished. I can fully recommend this product.
