All of the belts are very cute but once you start moving around while wearing them they come open and fall off. The links on the black belt completely fell off the belt. :(

Give you 4 ports for charging (two ports on extension). Long enough cord to run extension to the back seat. Available accessories include clip to hang it and mount for headrest. I still need to test to charge all 4 devices at once.
