When I bought an early USB-C MacBook Pro in 2017, the keys we didn't have weren't of the best quality. I bought one from B&H that used two inputs but had an SD card and 2 USBs. The problem was that the MacBook turned off at the slightest movement. It fits perfectly. It doesn't come loose at all: the cards are inserted well and stay in place.
