This is a great tool to carry in any car. It is so compact compared to all other air pumps we have. I like to have a backup plan just in case. It's not the fastest car tire inflator, but it won't help in an emergency. I wear it on my 2008 Scion XB with small tires and it fits perfectly. We tried it on our oversized 37-inch Jeep Wrangler tires, and while it inflates them, it definitely needs a break to cool off. This compressor is not really designed for oversized tires. I like to have a flashlight in the car and it's easy to find the button in the dark as it sticks out. On the other hand, it is easy to turn it on while driving in the car. I opened the tailgate the other day to find the flashlight was on, I don't know how long, but it lost about half its charge. That brings me to another point. The included drawstring bag is almost useless. It barely fits on the inflator and allows you to press the buttons when they aren't intended. The attachments won't fit in the pocket without crushing them and even then the hose is longer than the depth so you can't close the pocket. It's pretty easy to use. . Then set a calendar reminder to charge it every few months. I love it and other than the above issues which could be solved with a hard case, I would order again. Many Thanks.
