Write speeds are disappointing, but it works still, so no biggie
FAST reads! Specs say 45 MB/s; I got 75.8 MB/s! (Transcend USB 3.0 card reader in USB 3.0 port) Works well for my 20 Mpix camera
Not a full con, but ho-hum write speeds of 20 MB/s (Same card reader and port); Since I bought it for a camera, write speeds are kind of important
