The side contact on the plug end is a bad design. It bends in and looses contact regularly. I am now buying this products replacement and throwing it away. Find one with a dual sided plug or with a spring behind the contact. This just bends in.

I already own a different two-port device and needed another one. This works very well. The short cords add some flexibility to a crowded dash area. If your 12v outlet is near the floor or console, this is a great choice. If your outlet is higher up, say mid-dash, you may want to consider a product without the short cords.

I required a dual-adaptor for my car after acquiring a GPS system over Christmas, in addition to my iPod and in-car phone charger. This tool is invaluable; the short cords provide just enough reach, and the plug fit perfectly into my cigarette lighter. Great item!
