I have a LG WP50NB40 but it might be scarce these days. I wanted an external drive. Took about five mins to flash. I've ripped a few recent UHD blurays like the Barbie movie and Doctor Strange in the Multiverse of Madness without issues.

Anything on their list is fine. I have some random LG slim thing and it works.

The custom firmware allows them to rip 4K blu-rays.

I’m really glad I discovered this because I really didn’t want to spend on a 4K player or a PS5, knowing that this format is really on the way out.
