I tried Mana, but there were no flavours.
I have tried Bertrand too, but the konsistence was shitty.Than i bought Jimmy Joy, and I was happy. Ah yes, and I forgot: Mana and Bertrand are too unfriendly, Jimmy Joy got These funny e-Mails and pictures everywhere. 
Wanna try Soylent anyway, but I think i will Stay with Jimmy Joy.
