Works great with Switch 2’s dock
I specifically bought this for the Nintendo Switch 2’s dock. I was worried about if it had the right amount of clearance to fit but it fits perfect!
Note though that only the usb 3 (blue one) one will work, the usb 2 one (black) plugs in flipped.

Best to buy both, even if u just need one
It's better buy both and to assure to get the right one and gamble into buying one and are buying it bc u got the wrong one. Works as intended

They work as they should
But they wouldn't work for what I needed. I purchased these but the Steam Deck to take stress off the top USB C port when charging, but they're a bit too small to fit. I can find other uses for them. They feel really well abs built to last. Cables and ports seem very secure when connected.
