I pre-ordered my black one back in October 2018. I got it yesterday. I would assume they only had enough for pre-orders, and they won't have more for awhile. I only wanted the 2.4G but the Bluetooth version is in stock.

8Bitdo M30 Bluetooth Gamepad - Sega Genesis & Mega Drive Style - Nintendo Switch https://www.amazon.com/dp/B07MSN1NPC/ref=cm_sw_r_cp_apa_i_1yvECb98ZFPJJ

Just got these two days ago, absolutely loving them so far

Expecting these to arrive today, they've got great reviews and I'll let you know how they are in a couple hours 🙂

I also use Steam controllers for any games with joysticks/camera controls, or if I just don't feel like getting up to switch peripherals.

Sticks are expensive and doesn't really offer any "real" advantage, only invest in sticks if u have the budget or are willing to play fighting games for a long period of time, good starter fightsticks IMO are 8bitdo arcade stick, Mayflash F300 and Qanba Drone.

​

That said, consider 8BitDo M30 I've been hearing a lot of praises of this controller from the FGC subreddit, it must be good. I myself own a DS4 and an SN30. The dpad in SN30 is better than the DS4 but I mainly use the DS4 coz I have huge hands

Says in the product description that it can be used with a computer, but you have to use a USB cable.

Seems like you should get the Bluetooth version instead https://www.amazon.com/dp/B07MSN1NPC/
