Product review (3 stars): somewhat works
It somewhat works depending on the amount of space between your stove and the counter. There is slightly too much room between my stove and the counter top, so it doesnt stay in place firmly. I have to keep moving it all the time. But it keeps the food from going through the crack.. so it's better than nothing.  They should have wider selections of different sized lips for people who have bigger gaps such as me.
