The compressor arrived in a very nice carry case. The directions were clear and easy to follow. The features all operated as described. I tested the auto shut off feature and it was within a pound and a half as tested with a guage. Keep in mind that some of the pressure was lost while disconnecting the compressor. The power cord is of adequate length for a car, however, for a large SUV you might need to switch to a rear power port for the rear tires. It would be nice if the air hose was about 6 inches longer. It inflated a 26 inch bike tire from 0 to 45 PSI in well under 2 minutes. The light is adequate, however it would be nice if it were brighter.
Pretty much this was easier then heading to WaWa all the time to do my tires in the freezing snow.
- Function - As far as features and such go, this meets what you would expect from a car plug tire pump. It filled stuff and fast along with having lots of organizational space to put the cables from this device along with a case for keeping it stored. However, it did have one down side which was mainly the PSI reader was off by about 2-2.5 psi. It displays correctly before you start filling but then gets thrown off while filling. My advice to fix this is to just raise your setting by 2 psi to compensate.
- Quality - The quality overall was pretty much as expected. I didn't see anything that stood out as a defect with this.
- TL:DR - - Pros - *Filled items as expected. *Has storage for cable organizers etc... along with a carrying case. *Quality overall seemed fine in general.
- Cons - *PSI reader on it reads perfectly until you start filling and then is thrown off by about 2 PSI over what it should show. *It's fairly expensive.
Every car owner should has it. You never know when you would need this in a case of emergency, so I keep mine in the car at all times. Easy to use and very effective! Also works great on bicycle wheels! My favorite feature is cut off mechanism. You just set the desired pressure, hit the button and it will pump untill gains proper pressure and then automatically shuts off. Worth the money I paid. Recommend
