Some who gave this product one star wondered if they received a genuine Motorola product. After seeing those reviews, I was concerned, as I had returned the charger Verizon gave me when I bought my Motorola Q because it broke upon my first use of it. I needn't have worried. The product did not have the feel of a knockoff - instead, it felt appropriately heavy, it fit snugly into the cigarette lighter (now being called a power source more and more), and worked beautifully. The M logo lit up with a pleasant glow, it looks cool, and my phone was recharged.So - it does exactly what it's supposed to. Perhaps those who received what they thought was a knockoff bought a used product?
