I like the product itself, but opening it was a struggle at 1st. The scoops are huge and cramming 4 scoops in one smoothie would be such a struggle to consume for me. Luckily, my goal is to maintain size instead of gain size, so I can still get my fitness goals with just one scoop. Also, I like the taste. The inconvenience of opening it is my only real complaint about it so far. The fact that it would be very difficult to blend without a blender would have been a complaint of mine as well if I didn't already have a blender at home, otherwise, I have not other complaints about this product.
