Well, there are first procedure cases which didn't go well too: https://www.hairrestorationnetwork.com/topic/65602-dr-mwambas-fue-2200-grafts-work-7-months-review/ https://www.hairrestorationnetwork.com/topic/66589-1935-graft-fue-hair-transplant-nw2-dr-mwamba-brussels/page/8/
and there are simple touch ups which didn't go well: https://www.hairrestorationnetwork.com/topic/67566-repair-procedure-7-months-can-i-expect-much-more/
and there are repair cases from @Ajamilo@HappyMan2021@RTC who have their complains about their density and growth percentage.
In comparison, there is simillar (or smaller) amonut of success stories from independent reviewers. This ratio of successes and failures is just worse than in other recommended clinics and that's a fact. Maybe Dr Mwamba indeed have too much work, in addition working in the night must make him and technicans tired (and then people make mistakes easier) and long time with grafts outside of a body doesn't help too. Of course we can argue that this style of working doesn't make a difference - but again, the ratio of successes and failures speaks volumes.
