Verified Buyer Top 50 Contributor Reviewer: Anonymous Location: New York City Age: 45-54 Experience Level: Power User Owned Product: 1-3 months Rating: 3/5 Replacing the same model that became unreliable right after the warranty expired July 25, 2016 So far this one is working, no lost discs. It replaced the same model I ordered a while ago to set up a dual BluRay burning station in my old MacPro tower. That one became unreliable and would stall while burning either DVDs or BluRays ruining the discs.

I still have it in an external enclosure as it reads fine. The other BluRay burner in the MacPro is an older model from LG and it is doing just fine.Perhaps I just 'lucked' out and got a bad one.
