Well, I have learned my lesson with LG optical drives. Just got mine back from RMA (with LG as it was over 30 days)... they just sent it back to me. Warranty void because of an almost microscopic ding to a corner (which wasn't there when I sent it).
The thing worked for a couple of weeks, but I didn't have time to return it then. When I finally did, I had to deal with LG. What a joke.
Probably didn't help that FedEx THREW it across my porch. Yes, threw it. From the top step to the front door. My mother-in-law was home and saw it through the bay window. Dude never set foot on the porch at all. A line high arc that covered some 12 feet or more. Got to be great for electronics.
