I absolutely adore this casserole dish! it's a good size that holds a heafty amount. it being lightweight makes it easy to pull out the oven without strain and the curved top edges make for a good corner grip without worrying about sticking your hand in the hot food you're pulling out the oven! they clean up easily enough since they are completely smooth inside & the outside is a bit porous like hard plastic with a tiny amount of grip to it! there's been no color staining yet... hopefully it wont at all! 
since we haven't had much for leftovers (big family), the top hasn't been much use to us, but it fits nicely & i bet this would be great cover for the fridge! i've never used anything but thick pyrex for my baking dishes. 
**please dont hate me, faithful pyrex lovers**.... but i really do think these are fantastic! i cant wait to get other sizes!!
