You can plug in cards separately, eject cards individually, and swap between them without issue. There was no slowdown with multiple SD cards being read thanks to Thunderbolt 3 connectivity, and there were no issues with one card ejecting the others when being read. High-end cards, like the Sony SF-G128 or the Lexar 1667x will push this performance, but the average SD card isn't going to come close. And there's still twice as much headroom for improved performance, as the reader is capable of hitting about 312 MB/s read and 260 MB/s write speeds. With the Lexar 1000x UHS-II SD card - about the most performance I need for general photography work - I got back 145.2 MB/s sequential read and 98.3 MB/s sequential write speeds, both the upper limits of the card. Thanks to UHS-II and SD 4.0 compatibility, the GTR360 offers some impressive read and write speeds, especially for professionals using high-end SD cards. Media pros drowning in SD cards can get back in control with the six-slot GTR360 SD card reader.

All slots have smooth action, and everything on the reader is machined smoothly. These are fringe cases and unlikely to happen, but they're a possibility. Accidental presses can release these cards without them being ejected properly. Several times I had the adapter and my laptop on my lap without noticing that the reader had fallen between my leg and the chair.

It's a nice feature, though I know some people would prefer the friction lock on a portable device like this. Push in to click and lock, push in again to unlock and remove the SD card. I expected the card slots to have a simple friction lock - push in and pull out without any sort of hold - but they are instead the type that locks the card in place when inserted.

The front edge of the adapter houses all six SD card slots, each with their own blue status LED to denote which cards are in use.
