He got what he paid for.
In short (ha!), he got a magnifying glass.
Technically, then, he wasn't scammed, because holding the magnifying glass to his, um, equipment, makes it at least look bigger, no?
And the magnifying glass came with some very helpful safety instructions: Don't use it in the sun.
Doing so would surely be more painful than falling for a scam.
The lesson from all this: If it ain't broke, don't fix it.
