Why all the hate?
"The only people who will purchase these will be magnificently well-endowed men, who frankly shouldn't need to measure, and incredibly snarky women, who frankly shouldn't be allowed to.
Such a ridiculous view. For starters I doubt most people would waste their money when rulers are plentiful, less expensive and more accurate.
Also, I very much doubt that that condom has the width to fit some of the 'magnificently endowed men'.
Nice idea but I doubt there's a market for it.
