CarryGuard - pepper spray disguised as a cellphone

We assume the idea behind the CarryGuard — a can of pepper
spray camouflaged to look like a cellphone — is the idea that you can carry it with you inconspicuously (nevermind
the racecar red) while traversing dark alleys and other dangerous locales. We suppose that might work — if your
would-be attacker isn't a skilled cellphone thief. A more effective disguise might be one that's less
ostentatious, like, say a can of soda or a pack of cigarettes. And as long as we're redesigning this thing, can we
replace the pepper spray with something more effective, like maybe a
Taser?
