Like a bunch of others, I’ve bought a whack of 8BitDo controllers and all of them have been great, but the price varies.
I’ve been using my controllers with the BLE xbox style adaptor, the 2.4ghz adapter, normal Bluetooth, and wired for when I dock my Deck to the TV. Best performance has been the 2.4ghz and wired for me, but not all of them will work with the 2.4.
