Edit: I have since earlier, filled this thing up with water and then turned it on its side and shook it like I wanted candy to fall out. No water leaked. I am not sure why it leaked on me before, perhaps positioning of the lid was an issue or maybe it was because the cup was just out of the microwave and heated. But at least when cold, the water test did not leak.-----Nice little bowl for making the smaller 2 cup instant soups, but don't expect to fit all 4 cups in there. You can see from the picture that 2 cups fills this to significantly, and it's almost too much when you have it on a rapid boil even with the lid on. Soup spouts out the vent hole and gets everywhere.That being said, I added kluski noodles to my Lipton soup mix and tossed it in the microwave. It took the standard few minutes to get to a boil, and then I put it in for another 3 minutes at the boil. Noodles were fine. Minimal clean up due to the lid. It still did a little spurting due to how "full" the container was but i'm not sure if it was the fullness or the combination of the soup mix. (You know how certain things on a stove top boil over if you just look at it funny? Like that.)As for the lid, it is not a perfect seal, and I don't think it was designed to be. It's a lid for keeping your stuff from exploding inside the microwave, and for that purpose it works well. Don't throw your stew or egg drop soup in it and expect it not to leak if it gets tipped over. It will. Keep one at work for being able to heat stuff up without being "that guy/gal" that exploded their lunch all over the communal microwave? This would work well.Pros: it has a handle. Praise the gods of handles-- no, but seriously. I love handles. I love handles to carry hot boiling things out of microwaves without doing the hot potato dance. Mine was blue. I love blue. Score. Works for packet of Lipton chicken noodle soup (just put a paper towel under it in case the vent allows a little too much water out the top) The lid works for what I think it was designed for-- keeping the spatter out. It isn't sealed though, which is my only complaint on what would make this thing better.Cons: Not sealed, frustrating if you want to port something in your lunch bag and save a step of pouring it into the cup to use it. Not (quite) big enough to prevent a little boil over for 2 cups of soup. (This may depend on what soup you are making. I have yet to try Mrs Grass or Knorr vegetable soup mix) It says 4 cups. 2 cups + soup mix + a handful of noodles (which did not raise the level) is pictured below. You can be the judge on if you think it "really" holds 4 cups. My opinion is this holds 2 cups of working/to be cooked soup. Now, if you are just heating up something that is not primarily liquid, this may not even be an issue, so please take with a grain of salt.Overall, this is still a useful microwaveable bowl. The handle makes me want to hug it to death. It comes with a warning not to cook oily stuff like bacon in it... (who cooks bacon in a bowl in the microwave? seriously? Maybe they mean bacon-potato soup?)
