A fair and convincing review!
Details on products Pros/Cons, your motivation in doing this and precise informations make me confident about this product and how to get the best of it. I hope to listen and maybe purchase a unit soon.
I wish more reviews were like this instead of hidden ads with 'cons: no'
Thank you for this worthy read @Rockwell75

Incredible review! Got the Dunu Zen Pro and 7Hz recently and your description of both is spot on!

Excellent review bro, thanks for the comparisons.
FD7 is not my cup of tea, I will definitely give this a shot.
Nice description of bass with homeopathy
