So I saw these when I was just browsing Marine Depot but they seem pretty rare here on R2R in people's builds. I know they only came outa few months ago, or so it seems, but it looks like a great idea. I am just wondering what your thoughts and opinions are on it, if you've used one, or if you would use them in the future?
