This is the perfect size for my lunches - salads, soups. It fits perfectly into my lunch bag - doesn't add any bulk at all. Have gotten so many compliments on it already.
The 2-tier and 3-tier containers are actually too big for my lunch and this is the right size and keeps things separated. It also gives me room to fit in my lunch bag for a water bottle, fruit, etc...I also noticed that because of the smaller size, the snaps are easier to open and close. This is great!
I was excited to get this product but I haven't had the chance to use it yet. Read reviews that it leaks, so curry take out is out of the question as is anything liquid.
