I bought this charging station roughly a week ago, it works great in charging my old controller as well as the new controller I bought at the same time as the charger. But I did notice sometimes when I put the controllers on the charger and push down to charge, after roughly 30 minutes to an hour the red charging light starts flashing red. Not sure what it means or what the issue is but if i pick the controller up and place it back down it goes back to solid red
