I love the idea behind Queal (and similar products), but I'm so sorry that you've changed your products that much. The new mixture is very hard to blend. Even if I shake a lot, turn off and on the cap during the proces, and let the shake stay in the fridge over the night, it still is very thick, full of chunks and hard to drink. Even more: The new bags are very nice, but they are extremely unhandy to pour from where the old bags was extremely easy. I never used to spill, now I spill if I'm not extremely concentrated and uses a spoon (it's easy in the beginning of a new bag, but the hard shape of the bag makes it very difficult to get the last portion out of the bag). I've now started to use a scissor to cut a hole to pour from. It works - although I still do spill some of the mixture, which I never did with the old bags.
To cut in short - the old version was much better to handle and to shake. I'm thinking about buying a small blender instead, but it will require more work than it used to - which used to be one of the advantages before that it didn't.
I'm still sticking to Queal, but I'm afraid I will be looking at your competitors now.
