Product review (4 stars): the fit is almost perfect, must have uneven cabinets
I bought 2 gap fillers to be used on each side of my stove and permanent cabinets. I wanted to prevent spills going down the very narrow openings.
Because of the narrowness I cannot use one filler as it was intended, however, I use it anyway as the magnet is very strong, it grips the stove tightly and the space filler sits over the space making the sliver opening somewhat covered. On the other side, the fit is almost perfect, must have uneven cabinets???? If I did not have such narrow openings, I can see this product doing a very good job of preventing "things" fall or drip down the sides of my stove.
In my opinion (only) the fillers are short about 2 inches. With the fillers touching the wall, they do not reach either the end of a standard cabinet or standard oven. My one recommendation is the fillers should be about 1-2 inches longer.  This is why I give this product for 4 stars
