Product review (5 stars): the happier I become
I don't normally write a lot of reviews on products unless I feel that they are outstanding in some way. I have been using this product for a couple of weeks now and the more I use it, the happier I become.
I just recently discovered silicone lids on Amazon. All I could say after receiving them was, "WHERE HAVE YOU BEEN ALL MY LIFE?" LOL.
I purchased a set of round ones to fit on my pyrex dishes and round pots/pans and then I purchased this rectangular lid from CMS Trade Group for my 13x9"  bakeware all at the same time. The silicone lids are all that they are cracked up to be. Because they are silicone and can withstand high temperatures, you can use them in the oven, on top of your pots and pans while cooking, and just put them on top of your dishes when you have left-overs and put them in the fridge!. The pictures they have on the description, where it seals so well that you can actually lift the dish up by the silicone lid is actually true. It won't withstand you holding it like that for a great length of time or anything, but it gives you the point that if you are using it to put away some left-overs, you are getting a good seal so your food doesn't dry out!!
Something that sets this particular lid apart from some of the rest on Amazon is #1..the price!! This product was definitely the most reasonably priced one on Amazon!! and  #2,  I really liked that it has the ability to be hung on a hook (which some of the silicone lids DO NOT. After receiving my lids, that particular feature became very important to me (Esp when you see my pictures!)
In my kitchen, I have one large cabinet that was just for pots and pans with their lids. I have another large cabinet that was for my Pyrex dishes and their lids. For my pots and pans, the lids for those took up half my drawer space. Since receiving my silicone lids, I have taken all of those lids out to the garage and just have the silicone hanging on a hook in the cabinet. IT HAS COMPLETELY GIVEN ME SO MUCH MORE SPACE IT IS UNBELIEVABLE!! The silicone lids are SO versatile because not only will they fit and seal on a 9x13" rectangular pan, but also smaller. I have also used it to seal a Pyrex dish that was 8x12".I recommended this product to all my friends and family.
