8bitdo, probably.

No it was a different brand.

128kb is a youtube channel that covers a lot of handheld Pcs and specialise in controller reviews. If you check it, the latest switch 2 controller they tested seemed good.

But I'd wait for the Mobapad M6 variant Switch 2 version.

They are split joycon that are very much like a traditional controller split in two. They can be used as joycon in handheld, or split joycon for TV play, or connected to make a normal controller.

The M6 switch 1 controllers actually have an accessory where it has magnetic rails to adapt it to switch 2.

Aliexpress sells them too

I had The misfortune of popping into a Walmart today till I dropped by the video game section. This location does have the Metroid prime 4 demo. Looks impressive. I would have played it, but some fat guy had parked it in front of the kiosk, and there was no getting around him.
