I had a couple of play and charge kit/battery combos but I found the batteries did not last long at all and I kept on having to plug the controller in. I may as well have had a wired contoller in the first place!
I then went back to normal batteries but used two seperate controllers which in the end which was a pain (especially when both sets of batteries ran out!) - but at least the batteries lasted.
This solution is the best of all.
I just play with one controller until the supplied battery runs out and then swap it with the other controller that has been left charging on the station.
Just pick up and swap the controllers and you're good to go again immediately. No more need for extra wires - no more searching drawers for spare batteries! No more missing out on your record kill streak!
Excellent product! Buy it.
