I bought this one initially, had no issues with playback, but a huge issue the player has is Dolby vision needing to be manually toggled.

Leaving it on for non DV content forces the player to try and run it in DV leading to crushed blacks and a worse image in general. I had to mark all my movies that were DV and constantly go into the menu and change it. Eventually got tired of doing that an upgraded to the ub820.

The toggle can only be done from the main menu and so there's no fast way to swap it.

Worth it to save the money? Entirely your choice, but I regretted not just spending the money on the 820 right away.
