Product review (4 stars): Yes, they're flawed but compared to what?
This is the second set of these gas range liners I have purchased, so you know I must have been satisfied with the product. I agree with the critics on this page that they are flimsy, but they need to be flimsy to be able to fit a variety of ranges out there. And yes, you have to trim it to fit your particular range - another necessity to be able to fit all ranges. However, there is nothing out there that I have found on the market that does the same thing. I put mine in the dishwasher to clean so don't have to hassle with holding it down to clean. And yes, they eventually get dirty, too. I expect that more of these will be invented with even better features, but for now, this is what you get. I'm just glad they have them available because it makes it so much easier to clean the stovetop. Food doesn't get burnt onto the stovetop.
