I haven't used the new ones yet, but I have 8 of these bowls by pyrex and added an additional 4. They fit two in my lunch bag (long hours, so I bring brunch and linner) plus the glass takes mild abuse without chipping just fine and cleans much better than plastic which  I kept having to throw away due to warping, acid discoloration and bacteria hiding in places that won't wash away. Lid stays tight after washing in the top spot of the washer. Great product--I always buy pyrex these days.
