The product overall is fantastic. I love the mini-hoverboard and it goes great with my Funkos. The 4K video is supremely exciting to see. With HDR, details and parts of scenes "pop" revealing or drawing your eyes to things you may have never noticed before, specifically set dressing and background action. Even for someone who's watched these films almost every year since they came out. However, other than the fact that the discs are held in cardboard sleeves that could easily lead to scratches instead of plastic cases, there have been video integrity issues with the 4K discs for BttF2 and BttF3. The video is corrupted at certain (multiple) points in the movies. They last for maybe 2 or 3 minutes total and the audio is fine but it does detract from the otherwise gorgeous experience. In the end, it's amazing to see all of the content in one place and the mini-hoverboard is fun to play with.
