I wrote the review stating that the bowls are inaccurate. If you read my review thoroughly, it states that the bowls are accurate for liquids measures (such as water, just as you stated). The bowls are not accurate for dry measures. Try it. Pour your cereal into the bowl for the desired serving size according to the lines in the bowl (usually 3/4 or 1 cup on the nutrition label). Now weigh just the cereal. Is it the same amount as listed on the nutrition label (e.g. 1 cup = 60 grams)? Probably not. I just wanted people to know this and not to rely on the measuring lines for everything. It's really really easy to use a scale. Just set your bowl/plate/cup on the scale, zero it and add your food by weight according to the label's serving size weight and how much you'd like. This doesn't work for liquid ingredients that are labeled by volume, not weight.
I do agree that the bowls are cute, have great shape and hand held feel to them! My husband loves that he can put a whole can of Progresso soup into the large ones without overflowing like our other cereal bowls do.
