Review on 💾 32GB U1 MicroSD Card by Unirex with SD Adapter and USB A to USB C MicroSD Reader - Compatible with Laptop, Tablet, and Smartphone - Supports MicroSD, MicroSDHC, and MicroSDXC by Tom Lawson

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.
