We were looking for supplemental shake for my son who is constantly moving in and out of the house for school and sporting events. Not so much as a meal replacement but just something nutritional to add to his day an take on the go that will supply the needed vitamins and also taste good. This definitely hit the mark for us. Although we mix it only in water, my son swears it tastes like chocolate milk and very smooth and easy to drink he absolutely loves the taste. It's pretty easy to mix but I do have one of those hand blenders which makes it much easier, but you could easily mix it with a spoon and not feel any chalkiness, you just have to make sure you mix all of it properly but that's a small nuisance. I am always looking for products that don't have all of those terribly added preservatives and I feel confident my son is getting the nutrition he needs without all off of the terrible additions some other products have. Overall very satisfied with this product, have already bought it a pretty consistent basis. If there is anything bad I would say is that I would love to have a bigger version of it, but it's a small issue that definitely does not warrant me taking any stars.
