Change tires quickly and easily with much less effort. From time to time I drive on lonely roads. Mosquitoes and biting insects often plague these streets. I love having this in case I need it. Faster is always better when you're getting eaten by bugs when your hands are too busy to knock them down. I love that I don't have to use the jack that comes with my car. It's much faster and easier. I tried it for testing purposes and it is very easy to use. It plugs into the cigarette lighter, you put it in the right place and turn it on. It lifts your car quickly and doesn't make you sweat. For a quick tire change I recommend the purchase of an impact wrench with an Allen key. Although I'm a woman, I prefer to take care of everything on my own. I often pull a horse trailer alone and need to be self-sufficient. That doesn't mean I can't work smarter instead of working harder. It gives me the confidence that I can walk on my own and not have to think about what ifs. That makes him worth his weight in gold. This would make a great gift for a college grad or your teen. It is well made and very easy to use. It is compact enough to be stowed under the seat or stowed in the trunk. I hope I never need it, but I'll be grateful if I ever need it. I will be getting one for my elderly dad for his birthday!
