For more than 1 month in use and does what it should, reads quickly a Blu-ray and the output has a super quality. 3D films are also perfectly. Negatives I have not yet found but I use it only as a playback device of DVD or Blu-ray, I have smart TV set functions and therefore they do not use the player. I had no high expectations but he has surpassed. I would never have expected such a Top functionality in the price segment.
