Flex sounded fairly interesting, but I wonder how they can sell without more review. I was expecting more standardized forms and language on their site than I got. The 'How it Works?' / 'Is it Safe' FAQs seems not nearly technical enough. No known expiration date, really? As a guy am I not meant to fully understand how the device works? Obviously the 'Try it Free' should have a way to email your wife, right? Or are men not supposed to recommend feminine hygiene products to their wives? One for $3.95 (shipping cost) per address is a great marketing tactic. Anyway, I get a kick out the fact this is a YC funded startup.
