I've been using this type of cobalt Pyrex bakeware for close to 25years now. They cook foods evenly and hold up well as long as an inexperienced cook (my son) doesn't try to pick them up with a pair of vice-grips instead of a pot holder. Beyond that they are pretty durable and hold up very well. Truthfully wish I'd bought more of the dishes that were available years ago when they were less expensive. I liked them well enough to pay the extra to replace the ones that were broken instead of just buying something new.
Was a little worried about the color, cranberry, but it worked out fine. Nice to find a baking dish with straight lines instead of curves at the bottom.
