I use Queal/Joylent for breakfast mostly (7 days a week). Also sometimes in the evening (1 or 2 days a week).
Compared to Joylent : * Their shaker is far better. Queal v3 shaker is too small (fill the powder in makes a mess anytime); I think the screw-on cap should be attached to the lid; the screw-on cap gets dirty to manipulate after shaking (the Queal gets into the screw). I always use my Joylent shakers for my Queal. * My shakes always stays at least a night in the fridge but sometimes it is not enough to get the powder totally dissolved. I shake it a reasonable amount of time.
I really like chocolate peanut and chocolate hazelnut. Apple pie and tiramisu a bit less. I didn't test other flavors yet.
