This is a fantastic system when you need to replace your battery in the wireless controller! Plus the fact you can charge and play at the same time is pretty much perfect...however, the USB plugin only charges the battery. I bought this thinking it would work for my computer, but it wasn't entirely apparent on the package. I suppose I could have done my research ahead of time, but why not add in the feature where it can communicate as a joypad with my computer too?I'll end up having to buy wired controllers instead of using this, but its still a nice battery unit.
