Review title: good until it stops working.
Product review: This unit works as advertised initially but not when plugged into car power supply after 20 or so inflations. I used it to inflate a slow leaking tire on my vehicle and to inflate my son's toys occasionally. I would return the unit but it has been over a year since I purchased it and it still works if I plug it in to a wall socket. Very helpful tool if it were more durable and reliable. As it is I would not count on this tool or purchase again!
