Material very good. Upscale 4K all DVD and Blu-ray automatically if you have a 4K screen and an HDMI connection compatible 4K. The 4K image is beautiful. All films are sublimated. Turbo charging speed. Very little wait. The sound is transcribed in every way perfect. Length and width in comparison important of my other drive. Not 5 stars only because the reader was unpacking his ill recovery shell (factory, I guess!). No major damage or malfunction, only the hull that was not properly clipped and including 2 legs were broken. Disassembled and reassembled everything properly without two broken legs.
