So far it's been really good. I have only tasted/tested two flavors, but queal really fills me up! Besides that i'm have trouble dosaging my meals, why not printing a weigth scale on the shaker (since you must know the mass/volume ratio)? I also think you might take example on joylent, who make a sport shake with special molecules and a caffeinated shakes. I have tasted joylent, but so far I can say that a "standard" queal meal, doesn't let me hungry at the end of the day. Lastly, I should note that funky fruit was almost tasteless for me.
