Aromatherapy isn’t new, and neither are USB-powered diffusers. The aptly-named Aroma USB says it all - it features a scented fragrance strip that dispenses a fresh whiff of pleasant smelling air whenever the air around you gets stale - perfect for those working in an environment where fellow colleagues are oblivious to their own BO and fail to take any action on their part regardless of numerous hints. A single refill is able to last up to a week - I would prefer to see this USB-powered device come with some sort of built-in flash memory to increase its usefulness.
