I think it's a real let down, that this sun visor as suitable for the EF 100 macro is touted here. The only thing that was ok was the packaging of the goods. When attaching the lens 2mm it equal to at least. Missing on the inside diameter, so that "nachfeilen" every thought of an order to use it but can, has become redundant. I've checked it with two other photographers again, but also where it was not possible to attach this part as supplied. So it was "return mail" back. The star is for packaging - Real shame about the effort and now lost another word about it.
