I have been using Pyrex bake/storage ware for many years and up until recently was satisfied with how it performed. That all changed a few weeks ago when I dropped one of these containers a short distance onto an arborite counter and it shattered into a million pieces!!! How I didn't end up with some of these tiny shards in my eyes is a miracle. It could have been so much worse. And I NEVER used these containers for cooking/baking ONLY for food storage.BUYER BEWARE!!!Read my full review of this experience and related kitchen horror stories at:myreallifereviews dot com
