We all have ways of coping with our forgetfulness, but the Great Find-All could solve that problem once and for all. You just attach the four transponders to items you don't want to forget, and then when it's time to go, just press the corresponding button on the remote control and each of the items will make its own little musical sound to help you find it.
Sure, there are single whistling keychain devices, but this maxi-model with its four satellites can cover even the most forgetful dolt. This looks like an Asia-only item for now, but with all the forgetful people stateside, it could be a sales bonanza here. For god's sake, bring it here now.
