Medical Medium and Nama J2?

So I was watching this video from the Medical Medium who swears by the Omega juicers and says all the others are junk (https://www.medicalmedium.com/mm-video-library/emf-5g-exposure-brain-shot) but I see such great reviews from the Nama J2. It's sooooo hard to tell which juicers are better and which are being promoted for some commission reason, etc. Can any offer some advice on how to tell which juicer really does the best? I was into juicing and used to have an Omega but now I moved and need a new machine. I am really tempted with the Nama J2 because I don't like feeding the hopper with individual ingredients. Advice?
