The charging dock works great. It's very easy to switch between my docked Steam Deck and Nintendo Switch. That's the best feature IMO, as it can be a pain to switch/re-pair on other controllers. Android isn't officially supported but my Nvidia Shield TV works too over bluetooth.
Like all 8bitdo controllers, the firmware update software requires Windows. That's a pain as I use only the Steam Deck and Linux. If Steam Deck is going to be listed as supported, it should really support fwupd so that updates can be applied. 8bitdo used to provide updates on fwupd many years ago and just stopped. fwupd allows for trivially easy updates without having to even install custom software - it really just works. Also the back grip buttons don't seem to work in Steam. Multiple bluetooth device pairing would be nice too. I can pair most bluetooth headphones easily with multiple devices. But controllers rarely seem to allow for this.
