I purchased the unit at the local Canadian Tire store. I've used in on my Sebring convertible's slowly leaking tire. The main reason for the purchase was for use on my '51 Lincoln Cosmopolitan. The car has a six-volt system so won't run the inflators that are plugged into the cigarette lighter/power plug. So, this portable unit is perfect to have in the old car just in case. I've mentioned this to several colleagues in the collector-car field. So far the unit has performed perfectly. No complaints.
Bottom Line: Yes, I would recommend this to a friend
