Shipping was reasonably fast (to Germany), packaging was sufficient and secure.
The bags of Queal are easily opened and can be easily closed in case you don't want to use several different bags for taste variety. Measuring the amount of Queal for 1 serving was easy with the included scoop, though I did have some leftover for the third serving with the recommended amount (3 1/2 scoops). So I changed it to roughly 4 scoops.
The recommended amount of water (400 ml) was okay with me as it tasted good. I don't recommend more water, especially the shaker bottle is already full with the water and powder combined. You might want to use less water.
I ordered the "Taste tester" with 7 different flavours and the results are mixed. I really liked the two chocolate flavours (cool / peanut) and banana tasted good, too. Vanilla was a bit too artificial for my taste, but it was nonetheless okay. Strawberry was quite tasty, too. I didn't like Apple Pie (too sweet for me) and Funky Forest Fruit (not a good combination with the oat flavour all Queal flavours have).
I recommend storing the readily mixed shaker bottle in the fridge and let it sit there for at least 1-2 hours as it improves the taste and texture in my opinion. Feel free to experiment with it, though.
I used Queal as a full meal replacement for a few days and only had food cravings on the first day. My body adapted well to not getting much solid food after that.
Overall, I can recommend it. The taste is surprisingly good (if you like oats) and the price is reasonable for a product that is 95% more healthy then all the things you can pick from the supermarket. It's just so easy to mix the servings for a day in a few minutes and not to worry any more about shopping and cooking regular food.
