What People Are Saying

Rated 1 out of 5 by from No support, no drivers. Support and drivers for this model are not available, and LG Support site was aggressively circuitous and unhelpful. While this model will play SOME Blu-Ray discs and most DVDs, it won't others. Runs OK with Windows 10, but cannot recommend based on complete and total absence of any kind of support.

Rated 5 out of 5 by from For Windows 10 Use Try VLC Media Player or Leawo The product description clearly states that this product is compatible with Windows XP, Windows Vista, Windows 7, Windows 8.1, Windows 8. It does NOT mention Windows 10 so please don't give a bad rating just because you didn't read the description carefully. Also, there are at least two free media players that can play Blu-ray discs. One of them is called Leawo and you can do a Google search to find it.

Rated 5 out of 5 by from Perfect performance The drive has been great. I use Windows 10 and so had to purchase separate software to control it. It would be very helpful for you to provide a free basic player program for it.

I received this for Christmas, and have tried what i can. I does not function with Win 10 at all. Will there be a driver or software release to make this drive compatible or will I have to return the item and purchase another one from another company?
