I purchased this based on the positive reviews. There were small holes at the bottom of my window fly screen. These were caused when opening the window, by pulling the screen back from the velcro that attaches the sceen to the window frame.
The Gauder tape did a very good job of repairing the line of holes. The adhesive on the tape, came through to the other side and is a bit sticky for a while. But the screen should last a lot longer now thanks to the Gauder repair tape.
