Should I keep or not keep my Sony UBP-X700?

I've had an X-700 for a few years and I've never had freezing issues. The only somewhat annoying thing that happens with my player is that on some UHD discs there is an obnoxiously loud humming sound when the disc loads, on the main menu, and for a few minutes at the start of movies I play. But then it stops and it becomes pretty quiet. Other than that, it's been perfectly fine.

The only skipping I have experienced (to date) was with a 1917 4K disc, but I tried that elsewhere and it must have been defective. Was sent a replacement disc and it works just fine.
