Hmmm I saw that review also and yes he is doing DFK someone asked be4! 
Well could be a fake review as well somone trying to drag his business down   i’m not sure about the competition in each city .His english is also on the point . 
But I can tell chemistry can’t work for every single person ! 
I assume u guys also don’t give 100% in ur job every single day  things happen!  Even if the person use chemicals and tries his best! 
deal with it 
None is perfect 
 And Lol he is 5’10 between 5’11 for sure  met him  like seven times ! 
 Hawk eyes on that video cover Hahh Never asked him about  it  but as I can see it’s huge difference from now vid like 4-5 years old
