I tried the LG UP870, and despite being $150 less (as of March 2018), this is a far superior player. The X800 looked okay too, but with Dolby Vision planned for the summer, this seemed the best option of the two. It’s odd Sony go with a lower product number with a newer player, but the X700 appears to be the new X800. Region free - it works well. DVD is always region free, and Blu Ray requires pressing colors on the remote (instructions are included with the player). 4K - it’s my first experience with 4K so cant really comment vs other 4K, but specs wise this looks like it will be great and future proof for a while. Only downside to this player is the remote. It’s very cheap and light. Oddly the remote (RMT-B119A) that came with my old Sony S5100 works fine with this player, and it feels so much better, so the old remote is now with the X700, and the new one is with the old S5100.. Update 2 months on: The player is still holding up very well. No issues at all. Plays everything I throw at it. Unlike my old Sony Blu Ray player with USB, this one doesn’t keep the USB drive active all the time so if you have a regular non-SSD USB drive, it will save your drive by it not being on all the time. When you want to use the USB, just select it on the home screen and it’ll start the USB up again. Seems there’s a sleep timer to save the connected drive from being on when it doesn’t need to be which is nice. SSD HDDs through USB work great but you really don’t need them - over USB 3.0 4K/2160p video files from a regular external HDD play perfectly well. Update 6/6/18: Software update M43.R.0175 out either yesterday or today has Dolby Vision now.
