Product review (4 stars): Great cover for my new gas stove.
Received purchase a week late but this was during the Xmas week. Installed gap cover between my gas stove and counter. Gap is about 3/4 inch on both sides and cover fits well even with height difference of about a 1/2 inch. So far have not seen any warping  after cooking with stovetop burners and silicon material sit flat on counter. I have not tried to wash covers to date but material seems to be good quality.
