The more compact than I found. The small arm of the device that enters the cigarette lighter, is moving in 3 positions which is very useful amplacement according to the cigarette lighter in different vehicles. Includes a USB socket No more Adapatateur cigarette lighter for each device, it is amply sufficient for all devices. Impeccable losqu'on on a trip to roaming. It is a complete product If faillait find a fault it would be the weight a little heavy, but it will not lower its rating however.
