I go to a lot of events where we take a dish to share. Over the years I have tried wrapping the hot dish in newspapers, or towels and various other ways that I soon forgot as I usually ended up with a mess to clean up. WOW is all I can say about the Pyrex Portable 4-piece set. It includes a large 9X13 oblong dish, a tight fitting lid, and a insulated case with just enough padding to be easy to handle. Performance Now it is so easy to take a hot dish and still have it hot when you arrive. Simply heat the microwave pouch about two and a half minutes. Place it in the carrier along with your hot dish and you will be amazed how long it keeps your dish the perfect temperature. Ease of Cleaning Clean up is so easy. The insulated tote is just a wipe with a clean soapy cloth and a good rinse. Let dry before you zip it back up for storing. The 9X13 glass is typical "easy Pyrex clean up," If you have let something sit for some time, you might find that clean up is easier if you let it soak a few minutes. Durability The insulated carrier has two handles that are attached to the case in such a way that they won't come lose and the zipper seems to be substantial. The case has a inside pocket where you can put your serving spoons etc. The dish is Pyrex glass so it is a good quality. and the lid to the dish fits tight enough that it did not leak. Design Great overall design. The heat pack fits directly under the dish so I did place a piece of foil over the pack to protect it from the hot dish. I have used this set to keep a Jell-O salad cold. I simply removed the hot pack, and place a cold pack on top of the lid. The insulated tote kept it super cold. Doesn't Stick Food sticking doesn't seem to be a problem with Pyrex but if you happen to burn something on just let it cool down and a little hot soapy water seems to take care of it.
