Product review (3 stars): Good Design - But Not a Good Fit
I have a stainless steel gas range top, and this seemed like a nice solution to the daily chore of cleaning around the burners. My stove is slightly recessed, with curved interior corners, and is flat and open across the middle. The product is much as described, but not a good fit to my stove, and so it may not be a good fit to other than completely flat surfaced stoves.  The openings for the burners are very small, presumably to ensure a fit for the smallest burners, however cutting them to fit is not as simple as implied by the rudimentary instructions, and getting a good fit is cautious process of trial and error even with good measurements.

  Once you get the openings cut, the next challenge is shape of the surface.  My stove has a recessed surface and curved corners, which the liners did not adapt well to.  I ended up slitting the corners about  inch toward the center, and then slightly rounding the remaining tips to allow overlap and still  effectively cover the surface.  It is hardly a perfect fit, but is workable, and the appearance is acceptable (not a complete eye-sore).

Pros: Material is as described, closely matching our stainless steel stovetop, and is relatively non-stick.

Cons: Difficult to get a nice fit around burners and cover the stovetop surface unless your stovetop is flat, corners are square, and burners are all very small and of equal size.

In my opinion, the installation method and resulting appearance were what you would expect from cheap disposable liners.  I gave this product 3 stars as a result of the quality of the material, but was leaning toward 2 stars based on the installation method and price.
