64GB kit purchased. The micro SD card is formatted as exFat and has around 59GB of free space, which is fine. It fits perfectly in a thin card reader, not too tight, not loose. To a card reader connected to the laptop's USB 2.0 port, I copied about 30 GB of video files at 12-20 MB/s, which is pretty good for USB 2 another card reader. The slim card reader is great because you can use two adjacent USB ports at the same time. Overall good value for money.
