Product review (4 stars): Works Well Enough
The gap caps work well enough for their intended use between the range and the counter top. Some reviewers complained about the tape on wedge part coming off or moving, and that is true.  However I am unsure if the sticky tape is actually necessary.  My gap caps stay put, and I remove them when I want to clean them! So I prefer no tape. I think the piece which inserts between the counter and the range should be a little longer to wedge better, but as I said, although not perfect, it works well enough as is.
