I am satisfied with my purchase. The device seems robust despite its small size. the tray for the disc also seems solid. Up here I mainly read the blueray and have had no problem (I use PowerDVD provides). It is highly recommended even essential to update the version of PowerDVD in order to provide better now benefited from reading the blueray (an update to v12 is available).
Only point of attention, the USB cable is very short is that costs him his 5th star. I have a NODE304 box (mini ITX cube type) and if placed over the cable is too short to reach the USB port.
