Simply put - the best DVD burner I have ever owned. I will keep this one until the day I die, or it spontaneously bursts into flames.
Super easy to install, I don't know much about the inner workings of a PC, and it took me only half an hour to get everythign set up! It burns DVDs super fast - a full single-layer DVD for me takes only about 4 minutes, 30 seconds...I have NEVER seen it take any longer than that. It's never had a failure as well - it has taken quite a few beatings and still works great!
Did I mention beatings? More like...nine layers of DVD burner heck. I have a year old daughter. She took to the special habit a couple months ago of pressing the button to open it, and hanging on the DVD tray when it slid out. Then, a week ago, I found her happily opening it, and sliding a pair of nail clippers into the burner itself. After those were fished out, I caught her a few hours later sticking a ball of cat fur into the burner.
And it still works perfectly. Not a single problem. Ever.
I highly recommend this burner, for it's ease of installation, speed, and sheer durability.
