I Just used this last week on my NEW OnePlus 8 . Worked well, was able to get most the bloatware off the phone (not much bloat really). So I did not have to install a ROM. First time I'm actually use any corporate rom software. I did have to reinstall google as I need android auto (AA) to work and AA seems to need some google stuff to work. Very happy, your GUI is 'easy' to grasp, no surprises. The 'save APK' option in case of emergencies takes some of the stress out.
