After driving about 3 people with flat tires on the side of the road in a week, I finally gave up and bought this and a tire repair kit. I bought it on December 8th, 2019. I used it for the first time on December 20th. I pumped up a colleague's flat tire to get her home. In general I like it very much. It fits comfortably on my car's toolbox and has multiple attachments. That's great. Highly recommended. Edit - I used it again on January 25th. Me and some buddies went to the arcade and laser tag while he was coming back from boot camp. My friend somehow got a nail in his tire so I took the wheel off, used the tire repair kit I bought to go with it, patched it and pumped it up for him. Got a free dinner from this? Still highly recommended.
