This is a great storage set. I like the modern clean look and it insulates food efficiently. I accidentally dropped one on its side and nothing spilled out and it didn't break. The see through lids are a great idea, because it gives me the flexibility of placing containers in any position and still see what is inside. I added this to my existing pyrex collection, mainly because I needed new lids since my 15 year old blue lids are faded (still work perfectly) and I wanted lids that match my current kitchen and these white ones do the trick.
