Product review (5 stars): Keeps food fresh,  and it's easy to use in many temperatures!
I have just started using silicone lids and am totally convinced that silicone is the way to go!  I love the looks of this lid and the color is so pretty.  The design is very attractive.  I use my Pyrex baking pans all the time and have been using up so much aluminum foil and plastic wrap without ever getting a good seal.  This silicone suction lid provides the most air-tight seal possible and will keep food fresher for a long time.  I love that this can go into the freezer and will help to keep freezer burn and freezer smells out of the food!  I put it in the dishwasher as soon as I opened it, but it's so easy to clean right in your sink.  I've used it in the oven, and it's SO much easier that using aluminum foil to check what's cooking.  It  works great to keep food warm while getting ready to serve. The dimensions for this lid are given are in inches.  The bottom of my pan of the same size is in metrics: 33cm x 23 cm x 5 cm.  I hope that this conversion is helpful. You can see from the shadow,  in the picture of the large pan, that you can lift a pan right off of the counter.  The handle is easy to grasp. This lid is also able to be used on a smaller rectangular pan. My second picture shows it being used on an 11" x 7" x 1.5" pan.  The seal is just as great.  I was able to lift the pan more than 12 inches into the air! These lids are so amazing that I wish one was made for my slightly larger Pyrex pan.  I'm so impressed with these lids.  I've always been curious about silicone suction lids and will be using this from now on!  This makes me wonder about silicone muffin pans! I can't believe that it took me so long to try silicone.  I strongly recommend this beautiful blue cmsHone Silicone Suction Lid!
