I have only today received the drive (03/25/2014), therefore statements about its reliability little. But should you, like me, to be technically gifted little, I can assure you that the exchange of that drive was done within 5 minutes, including changing the aperture. The drive is recognized by Windows 7 (64-bit) immediately and is working properly. I own a laptop MEDION AKOYA Mod. E6228, which was not listed in the list of compatible devices. This laptop is a no-name DVD burner was installed, the model name "SN 208" had what I could tell from the label on the drive. In addition, the version number was about "BB". So if you're looking for here for a replacement drive, you should be aware of both the model and the version number of your old equipment. According to dealers, the connections internal DVD drives for laptops / notebooks are not standardized, so you have to pay attention to the above-mentioned designations necessarily. My old drive held at daily hours of use by just under two years. If this should create the new well, one can not complain given the price. Strong buy recommendation!
