Received quickly, very good volume for music in the car and some cartoons for the weekend. Put a leach because really small for easily catch into the bag. Its size is an advantage for me because it exceeds little different USB (PC, tablet, USB drive, ...) and suddenly there is no America to snatch a gesture contrary malancontreux with long usb key. I have 3 like this one, this one in 32GB and 16GB 2 (first purchased for cars). I do not really pay attention to writing and reading speeds but no worries on that side so ... I recommend it.
