I had previous experience with Joylent, which I like. Queal is much sweeter than Joylent, that seemed like a better thing when I first tasted it, due to the richer taste, however by the end of first serving of Queal I realized it's too sweet. Queal always tastes awesome when you start the meal, but sweetness gets too overwhelming as you near the end of the bottle, and the aftertaste in the mouth makes you feel like you ate candy. That's my only complaint so far.
As far as the oil bottle goes, I'm not sure if I dosed it right, I'm not even half-way through the powder but it seems like I'm going to be out of oil before the powder goes out. My mistake though. I don't mind the oil if it's healthier than flaxseed in powder form.
