I drive a 2003 model vehicle and it only has ONE outlet for chargers, radar detectors, GPS systems, etc. I can only plug in ONE gadget at a time. This adaptor allows me an extra outlet! And it was VERY inexpensive!!!! I've only just started using it, so we'll see how it holds up. If I only get a few months out of it, I will feel like I got more than my money's worth. I'm hoping it'll last until I decide to buy a new car (in 2-3 more years) that'll probably have all kinds of extra places to plug stuff in, etc.
