Roulette d'alembert?

Hi guys I was wandering what you think about. D'alembert worth it? I saw this video and started thinking about using it. Apparently it seems to work as martingale does but with a tempting safety margin. i'm trying to avoid repeating previous bad experiences (martingale=budget burned) i'd like your feedback...according to this d'alembert works vs the objective limitations of martingale.
Someone who's practical with it? Does it worth it? It's fake? I'd appreciate any information!!!

:)))))))))) thank you guys
