Ha! I love this little guy. When I say little one, I mean gentle. I've had a portable tire inflator for, well, I can't remember when, but it's been in at least three cars. It was noticeably larger than this and not as impressive. I'm a big fan of avoiding gas stations to keep my tires pumped up. Aside from the clumsiness of the pumps, their effectiveness is sometimes spotty. With today's Tire Pressure Monitoring Systems (TPMS) you'll now be reminded when you haven't checked in too long and that it's a better and more convenient time to pump up your tires than in a rested and cool car on your doorstep. everything you would expect from a portable gas generator: it's fast, efficient and quiet. My old gas generator made a sound like it would tear up my driveway when I used it and it probably lasted twice as long. I've seen some questions about possible air loss when disconnecting the connecting hose, and it seems to me that the pump could be running slightly above the listed PSI as protection against this situation. The auto shut off when the set pressure is reached is a huge benefit as I can rumble in the trunk or work in the car without having to constantly monitor the pump. Can't say much about the tote, it's a silly little thing that can tear over time, but it's pointless when it comes to performance and value. If I had any quibbles it would be that I can't seem to turn off the light on the pump. Performance wise it doesn't matter, just an OCD related thing (why wear it during the day?). This is a great purchase at an amazing price.
