Bests & Worsts Reviews from Amazon

I've been shopping for a portable inflator so I don't have to go to service stations & deal with that clumsy contraption with the long hose, the 5-minute time limit & the charge. After reading many reviews & learning about the two basic operating systems, (rechargeable battery & the plug-into-the car's system) I decided on the cordless battery version. I was pleasantly surprised to find this brand that includes both type of chargers at a reasonable price. I charged the unit for four hours before my first use. I just got a new Altima & from past experiences, I know that dealerships don't bother checking tire pressures. I got out my gauge & found one tire with 50 psi, one with 38 psi & the other two with 42 psi. Since the maximum pressure listed on the tires is 51 psi, I decided to put 40 psi in each tire. I set the inflator for 40 psi & it automatically stopped where it should. Adding those two lbs. of pressure took 6-7 seconds. I verified the pressure with my gauge, which is pretty accurate. I liked the easier clamp-on connector instead of the screw-on type. Very little air is lost when removing the connector. The digital display is easy to read. The inflator is simple to use, even without reading the directions. I can't speak to its durability after only one limited use, but it worked as it should.
