My experience with Queal has been very good so far. Having tried both Joylent and Queal, I prefer Queal.
I like the banana and strawberry flavours. It would be nice it there was also a more savoury flavour.
I feel good on Queal and the occasional bloating is not too bad.
I'm not a big fan of the separate oil. I usually prepare my Queal at University, so I also bring the oil bottle. I would also recommend to describe the amount of oil to add in terms of number of drops instead of spoons. (As I won't bring a spoon with me haha).
