Product review (3 stars): Flimsy
These are quite a bit lighter and flimsier than the last Range Kleen set I ordered. One of the large covers isn't firm or heavy enough to lay flat over the burner. I just put them on the stove, so time will tell whether or not they'll survive typical stove-top activity.

Update: I've owned and used these for 7 months. I will not re-purchase the same item when these wear out. These get normal, daily use. I use them to cover the burners and remove daily for cooking. I set pans on them, wipe them down daily, and wash as needed with a sponge and soap. They do scratch more easily and are not as sturdy as the Range Kleen set I used previously, but are not a complete loss for the price. I'd still prefer a heavier material that is a bit more scratch-resistant.
