Review (4/5): Quiet, but max capacity is not much more than a cup
It really is very quiet! I haven't used ice in it, but just my regular protein mix and a collagen supplement. It could be a little bigger. With 8 oz. of liquid, it does the protein mix alone great, but can't handle mixing the supplement as well. You wouldn't be able to add more than a couple berries, for instance. Otherwise it's great.
