Retro designs are fun and all, but 8BitDo was wise to include some more modern features, like support for the keyboard to connect to systems via a USB-A cable, a USB-A 2.4 GHz dongle (which you can store in an integrated compartment), or Bluetooth Low Energy.
I’ve had mixed experiences. Their controllers are great, but the bluetooth controller adapter is a fickle and annoying piece of hardware.
