What are the best DVD rippers?

Recently get its free copy of license code on its back to school giveaway. It works well in loading dvd disc, even my disney toy story 4. Satisfied with the output quality, no visually quality degradation.

Got this dvd ripper in September, last year to help my grandpa backup his old discs. As for the normal DVDs, it works like a charm. But it doesn't read any 4k or blu-ray disc.
In spite of that, I still like this ripper. It has the pre-loaded iPhone profile, I don't have to manually adjust the settings for my phone. That's great.

Flagging this option since it's in violation of our promotion policy.
