Annoying Sonic Whistle Key Finder Flashing Light

Just as annoying and impractical as the original, they go off when you don't whistle them, and when you actually need them, they're really not that reliable. A great prank gift for that cheeky relative who asks for a £25 key tracker, get them a £2 one that will drive them insane. The batteries can't be replaced, they're not very robust, no bluetooth, no GPS...no use! For youngsters who were fortunate to never own one of these, they'll have no idea of the disappointment that lies ahead, as the packaging lists the benefits "NEVER lose your keys again", "Just whistle to activate the alarm", "With Flashing Light". For those old enough to remember the first wave of keyring trackers, they may love the retro disappointment, or best kept for a secret Santa gift if you want to stay friends! Non replaceable batteries Do NOT use if you really need to find your keys!
