Excerpt: bought this product the other day and have been very impressed with it so far. every copied disk works perfect with no crashing or faults. simple to install, just removing one screw from the laptop, sliding the old drive out, removing the screw catch and screwing that onto the back of the new drive. then just slide that in and put the screw in the bottom of your laptop and its ready to go. writing speeds for cds are superb, and the same with dvds.
