I've been a customer with Queal for about 8 months now and I simply love it.
The delivery is always prompt and everything comes well packaged. The shaker that you get is great (that round spiral sphere especially). All the flavors are good, especially the macchiato flavor. It took a while to get used to the smoother consistency of Queal 3.0, as I had sort of come to appreciate the grainy and a little chewy consistency of the older iterations.
I used to hate breakfast. It was always a dull, boring slog that took way too long and left too many dishes. Now I simply drink my queal in 5 minutes and I'm on my way!
