No one will have any idea that robot keychain you are carrying around is also a USB drive. It can also be imprinted with a logo. This is one promotional product that won’t end up in the bottom of your customer’s desk. And no need to worry about people looking to steal it, with the basic product having a capacity of 256MB it would be more fruitful to just go to the store and buy one with a useful capacity.
