So here I have bought 2 boxes 4g dvd verbatim, this box sold 20th, I am very satisfied printable verbatim brand is certified above, no failure, the thing that sold the box with 15 ec is just the opposite with my pc recent does not recognize dvd and cd on any certified brand, ca should not be verbatim but are sold as if c the second time I do the test, on the 5th of brand sold 50% of DVDs in the trash, go merry christmas friends
