For what it's worth, I bought one at Costco about a year ago, works fine for starting my 124 diesels when the batteries get low. I do not like the computerized 'feature' that decides if it is really hooked up to a low battery, as I had hoped to be able to use this as a 12v power source at the pick-n-pull. Mine cannot be used as a simple 12v power source, you need to either connect it to a low battery or figure out a way to fool it.
