Pros for this plaque: it's dark so you can easily see the different thickness of the reed. It's cheap. Cons: It's too thin (doesn't support the reed when scraping. It's not galvanized or coated so it rusts super quick. I have only used this plaque for about 1 week and it's already rusted. I'm going to search for a plastic or thicker metal plaque that has some kind of coating.
