Pyrex 6021224 Storage 10-Piece Set, Clear with Blue Lids

Read some reviews about how the lids "warp" with time or don't fit tightly with time... well, I've never had this problem (???)

But I should mention that I NEVER heat the lids with containers in the microwave. Ever. If I need to cover the container to prevent splattering, I use a glass dish or something of that nature. I just hate heating plastic around food (possible chemicals leaching into the food and all)... even if the stuff is supposedly microwave-safe.

It's the whole reason I bought these glass containers in the first place, after all. So no warping issues thus far.

PROS: Overall I am happy with these dishes. The round plastic lids seal very well. They are snug, but not exactly water tight. The square lids do not seal as well along the sides but do stay on. Being made of tempered glass, the dishes can be used in the microwave, oven, fridge and freezer. They are heavier than thin plastic containers for taking food to work, but you avoid most of the plastic leeching that happens with those containers. The lids can leech plastic if left on loose during reheating due to the condensation that collects on them. Except for the bowl rims (see "CONS" below), these are fairly durable dishes.

CONS: The major down side to these are the glass rims of the round bowls. They are the weak spot and can easily chip or break. STACKING the bowls with out their lids on is NOT advised. This is especially true for the smaller "2-cup" size bowls. Due to the crystalline nature of glass and very little tapered angle (the sides are almost vertical), pulling 2 bowls apart can shear off pieces of glass from the rim of the bottom bowl. You may not be aware of this when it happens and there is a danger that small shards of glass may be left inside a bowl. Those of you with children should be aware if this point. The square dishes do not appear to have the stacking problem.

When using a dishwasher, you must be careful to NOT allow the rim of one bowl to come in contact with another dish. Otherwise the water pressure may rock the bowl back and forth resulting in impact damage and chips to the rim. I suggest trying to move or wiggle the bowls by hand to check the range of motion while resting on your dishwasher's rack. With a little experimentation, you can find the right spots to load these bowls safely. This is mostly a problem when the bowls are at an angle. The best way to load them seems to be securely on their side. Just be sure they cannot move around and are not tipped back (which will trap water and soap).

Pyrex appears to change their manufacturing frequently, which one assumes is to improve the product. The color of their glassware has a darker blue-green tint than they did a few years back. The rim (lip) of their dishes have a more rounded edge than before. However, the issues I describe above are still present. It should be noted that the rim weakness usually only results in small chips and I have not yet had a "fault line" or deep crack start in one with normal use. With over 2 dozen of the 2-cup size bowls I have only had one casualty when it was dropped from about waist height onto a very hard floor.

I should have read the size on the pyrex bowls, they were smaller than what I thought however the quality is good.

These are a huge improvement over any plastic Tupperware I've ever used. I've noticed that if I place a couple of cut up limes in these 5-6 days later they are still good to go and not dried out.
I just bought my second set today.

the glass storage containers are so much better than plastic. they don't get stained. and I've dropped one, didn't break!!!
