Are Fasst Company Flexx Handlebars a game changer?

I review the Fasst Company Flexx Handlebars on my Beta 450 RX. Is this a magic cure for armpump, hand cramping, and fatigue? Can they lessen the impact from a jump that was misjudged. Will they help with those insanely rough tracks? I used these bars about ten years ago and had some of the best races of my life. I am going to try them again to see if it is in my imagination or they are really that good.
