This is a great idea to keep things organized and the rechargeable batteries are a bonus as my kids can go through the alkalines like there's no tomorrow. The charging station can accommodate the wrist straps, but not any sort of silicone skin on the smaller controllers. Not too much of a concern, but anything to minimize how often 3 younger boys are trying to remove the skins in order to keep things charged while maintaining some protection for the controller (and each other!) is desireable.
The AC adapter is also smaller than the original Nintendo product, which helps make up for the fact that the adapter for the Wii U console has grown (vs. the original Wii) and we only have a limited space in our entertainment center to try and keep things hidden (and cool).
Overall, we're quite happy with the charge station.
