This is NOT a Lite-On. I'm not saying it won't work, (it seems nice) but IT'S NOT WHAT I PAID FOR!!!!! So, you pay 40 dollars for a cheap Chinese piece of garbage. FALSE ADVERTISING!!!!! What the heck is going on here? I blame Amazon.Also, this thing is almost 2 1/2 inches thick, forget about putting it in your laptop folio.Last: Forget about the travel pouch, it doesn't come with one, it's bulk shipped in a plastic bag.
