Without modern electronics, mankind would have limited access to Bach's symphonies, Hitchcock's films, and Bob Saget's dog and baby voice-overs. Stock up on entertaining appliances with today's Groupon: for $12, you get $25 worth of phone, laptop, and tablet protectors and accessories from BodyGuardz.

BodyGuardz's gear equips mobile-device owners with shields to prevent chips and dings and accessories to enhance the gadget-operating experience. ScreenGuardz protects and coddles handhelds with see-through sheaths such as the Apple iPhone 4 ($9.95–$15.95)— which attempts to stop shatters—and four-way privacy coatings that cut glare from light or jealous onlookers. Protective parents can cover cellulars in Clear Skins—an all-over barrier made of the same chip-resistant substance that protects auto exteriors—which come in packs of two for patrons who routinely call themselves on their second phone ($24.95). Clients can makeover digital telephones with fashionable print and artwork skins ($14.95) or soft black, white, and red carbon-fiber blankets ($19.95). An array of Earjax ear buds, such as the Gigs ($19.95), feeds high-def music to eager eardrums in three sizes. With the ease of a one-size-fits-all union suit, BodyGuardz's products can protect a wide variety of brands and models.
