The taste of Queal is OK, and I appreciate the variety in flavours. However, the design of Queal - bags, measuring cup and shaker - is bewilderingly bad. The bag has a very small mouth, making it very difficult to bring the measuring cup out of it without spilling powder everywhere. You also cannot pour it out without spilling. There is only one measuring cup, meaning I must carry it between work and home, as I have Queal in my desk and my kitchen at home. Lastly, the shaker is the only one I've ever used with a serious design problem. Every time I open it after shaking, Queal squirts out - onto my computer, my shirt (more than once), and my desk. I have encountered good and great shakers, but never one that actively made my life worse. I can't make Queal at my desk, and only make it in the office kitchen, and always have to wipe up some powder or some liquid Queal. This is a good product delivered in a hopeless way.
