Opened the box and found a very nice controller, plugged it in, turned on the switch and plugged it in. Firstly you can't check the battery level on this controller (or mine was faulty in that area), secondly it stayed connected for a total of 3 minutes and then disconnected from my switch leaving all bottom lights green. I would take this as an indication that the battery is not dead. So I decided to hook it up to play very unlucky I might add. I then decided to charge it overnight and try again the next day, same problem with plugging and unplugging after a few minutes but no success reconnecting to a wired or wireless connection. Wouldn't waste your money on this, buy a professional controller on Etsy or something before you buy this.
