Consumer Critique - Nesting Mixing Bowls with Blue Lids and Graters

I had a chance to review a set of nesting mixing bowls with lids and graters. 

 These have a lot of good features. They come in three sizes, so you can get the size that's appropriate for the amount of food you're mixing up. They're made of good materials. The stainless steel of the bowl is easy to clean, but the handles are a little more comfortable to grab than bare metal.

I really like that they are lidded. Sometimes recipes like cookie dough have to chill. The biggest bowl in the set is roomy enough that I can mix up a batch of cookies, and then I can put the lid on it while they're chilling. The smaller ones are good for tossed salads or other cool recipes.

The most unique feature is the embedded grater. There are three different types - small holes, big holes, and slicer - and they fit snugly in the lid (the lid has an insert that can pull out). This means that if you need to grate cheese or something else for a recipe, you don't have to try to balance a grater on top of a bowl - you can have the grater securely in the lid, and all of the ingredients go where they're supposed to go: right into the bowl. I was a little curious how that would affect the seal or whether it would be stable, but the way it's designed, it's a snug fit - you can swap out the lid and the grader part pretty easily, but the lid is secure when it's on.
