At the play-and-charge kit is an excellent product. You have to buy batteries or charge the batteries in an extra charger, but can continue playing while charging. If the battery when you turn off the console is not yet full, the charging cable to the controller is connected and charging stops automatically when the battery is full. After that you can then play several hours wirelessly. Had I written the review after two months, I was done here.
A few months later, however, things look completely different. Starting with only a few cable free play hours building the battery pretty quickly so far away that he can no longer be loaded. So I take advantage of all the good qualities nothing, because what was the real reason to buy is no longer given. I can only advise against the purchase, unless you do not plan to use the play-and-charge kit for more than a few months.
