Product review (4 stars): Great to seal off the dreaded spill over problem.
Wide Silicone Gap Cover are very handy to prevent the spilling down crevice problem. They are pliable and easy to wipe off. Silicone has a sort of grabbing attribute but is not permanent grabbing. These can be easy to bump out of their crevice space, so a longer vertical gap piece might aid to grab better and stay in place, so manufacturer might do well to add another 1/2" to keep this more in place. This is why I dinged them one star.
Like that they are Black since most newer ranges or stoves anymore are not white. I got these to replace the hard metal white gap covers but they were so narrow that liquids could still get past them at times. And being white I would spray them black but when cleaning the black would come off and I would repaint them only to have to repeat effort over. No longer will I waste my efforts. They are not highly shiny, but rather semi-gloss to satiny in reflectivity.
I have used them now a month or so and am pleased with their function.
