It's a good decision to buy something from AineZ Store on Amazon Marketplace, because they review customers orders carefully and this fact is confirmed by the partly handwritten letter from AineZ Store stuff, which I read. They thank to customers for buying product, and this mean that you will receive exactly such product, which you wanted to buy (from some of the vendors I have received a different product than I added to cart).
The discs of TDK BD-R DL 50GB 6x have good quality. The iso images of 3D movies amount of 42GB were burnt in about 30 minutes. I have Sony BWU-500S blu-ray recorder. The 3D films are playing with no problems from both, Sony BWU-500S and PlayStation 3 320GB.
I will buy always this discs from AineZ, because these discs are high quality and the total price (including shipping) is lower than in other stores, and AineZ transports from the U.S. (not from Japan or other countries that require a lot of time for delivery).
