Arrived in great shape, installed in minutes, works perfectly. To be more specific I was able to boot to internet recovery mode, format the new SSD, and install the correct macOS all with the drive in the external enclosure. I then opened the bottom of the Mac, extracted the original SSD with a single screw, and then swap the new into the Mac and the old into the enclosure. Lastly, I used migration assistant to copy the user folder. I was able to revive a failing computer, quadruple the storage, and increase the speed. Success!
