Product review (4 stars): Kohzie Silicone Stove Counter Gap Covers are worth buying
The width is sufficient to fill the gap between my oven and counter, but it would be better if the vertical part was about 1/2" or more longer. As designed, it deserves 4.5 stars, which I can not give. But even with this slight issue, the Gap Cover works well, without any issues. It does effectively prevent crumbs etc from falling into the gap onto the floor. It stays in place and is unobtrusive.
