Tested on three cards: Lexar 128 GB UHS-II (250 MB/s), Sandisk 64 GB UHS-I (170 MB/s ) c) and Samsung microSD 128 GB (90 MB/s). All gave stable results. In terms of performance, this is a solid UHS-II reader so far. There is an LED that should stay blue and will turn red once safely removed so you can turn it off. This is a good feature.
