Overall positive. Taste is good; flavours are not unappealing. On the negative side: - I dislike the fact that oil is required (no oil in sample pack, but I know the normal package uses oil). Many of your competitors have gotten rid of the oil (using flaxseed or similar) and I STRONGLY recommend doing the same. - Queal is 'grittier' than many of your competitors when first mixed. It's fine after leaving it for a bit in the fridge, but it requires a little more planning than the likes of Joylent which I find drinkable straight away.
