Okay, I wouldn't entrust my diamond stud to the Off Limits Voice Vault Toy, but for a 12-year-old nervous his buddies might swipe his 20th Anniversary Edition Game Boy micro, it might be perfect protection. The vault only unlocks when the owner speaks a recorded codeword (though I assume a sledgehammer would also work). If an intruder attempts to circumvent the vault's defenses, an alarm will sound. Such high-tech security can be yours for around $30. — Trevor Noren
