Query: Not designed to what is needed

It's nice that you can adjust the size of corner you need. The down side of that is... they come from the manufacture flat. When folding them, you have a open gap right at the corner, where you need the protection. I had to tape the corners closed, to make them work. They also need to be deeper, so they don't fall off so easy.
