Crave Flex is a classy, giftable vibrator; it's small, quiet, waterproof, silicone and stylish. Plus if "crowd-sourced vibration" piques your interest, consider that this vibe's four vibration patterns and four levels of intensity are based on the quantitative feedback of the first 100 testers. The silicone body balances just the right amount of pliability and firmness. The unique motor mount keeps the vibration in the bendy tip, not in your hand. USB rechargeable. One year manufacturer’s warranty.
