“Got out of my car one morning at work, and it was hissing. I pulled the car around back to give me some time to work on it without having a flat tire out in front of my business on a company car. It went all the way flat in 30-45 minutes. The next day I brought this tool I had gotten on Amazon Vine and set it up to fill the tire while I got my plug kit ready. I hadn't even taken it out of the case and really looked over everything so this gave me the chance. There are a few air attachments, but the one with the hose is all I needed. It screws in nicely to the side of the pack. It has a toggle to lock around your valve stem, which worked perfectly despite some doubts I had. I literally set the pressure, hooked it up, turned it on, and walked away. ”
