Completely satisfied with this device. Corresponds quite what I expected, especially reading via USB socket, a large number of formats and in particular certain formats: FLAC WAV MP4 FLV MKV which I held it is not the case for many Blu-rays readers. The image and sound are impeccable. In addition, I want to acknowledge the remarkable efficiency of service: 1 failed drive replaced in 2 days! after informing ... (no course fees) In conclusion I would recommend this 100% reader; and regardless of the unbeatable quality / price.
