I bought 2 of them because the price was really TOP! Maybe I'll make a present. LAUGH OUT LOUD! I've used it on two of my cars. 2001 Ford Expedition, Eddie Bauer, 4WD, loaded. Also loaded 2008 Infiniti G35, both bought new! This charger did it in 1/3 the time (8 hours or less) compared to one of the popular Washington state stores (G**ots). It costs 7-8 times more. For real! The device is SIMPLE and seems WELL MADE with USEFUL electronics. I hope this lasts long. I will be using it a lot as my cars have low mileage and the onboard electronics drain the batteries a lot. I highly recommend this item!
