When it comes to vibrators, the Crave Duet gets some things right: it’s got a discreet, travel-ready form factor, comes coated in body-friendly materials, and packs a rechargable battery. When you remove the water-proof extension to reveal a USB port, however, things get...unconventional. That’s because this vibrator’s powersource charges--you guessed it--via a computer’s USB port. With the soft-material cap detached the Crave looks like just another thumb drive. So no one will know the same laptop you're using to IM team members and slash through emails is powering up a fun, after-hours toy. Availability in 8GB or 16GB storage sizes helps make the Crave all the more invisible, just not any less awkward.
