Okay for the price, not microwaveable
Reviewed in the United States on August 28, 2017
These were a perfectly-sized replacement for my old Pyrex lids that were getting cracked after many years of use. However, I used to be able to microwave those old lids (and I did often, to prevent splattering messes). These new ones do NOT hold up in the microwave, as you can see in the attached photo. Two minutes in the office microwave, and the lid is permanently warped. It still fits the dish, but I won't be using them in the micro anymore!
