Since they got rid of the SD card slot (which I occasionally used with my two cameras), I was looking for something not crappy to replace it. Found this: https://www.amazon.co.jp/dp/B01KLT2AGG
Pros: Does a lot and looks good. Useful when necessary and stylish. Doesn't require carrying/remembering a microSD to SD card adapter as well. The USB-A plug is nice, too!
Cons: Blocks the other USB port
Minor caveat: Confirmed in System Profiler that SD Card Reader maxes at USB 2.0 speed, but this was also the case on the rMBP, and I don't think that my occasional use warrants a panic nor do my SD cards exceed that speed anyway for the time being! https://support.apple.com/en-us/HT204384
