Even after including all of the items we actually need in our lives, computer catalogs still have many pages left to fill. Fortunately, there is an entire industry working hard to invent useless and downright asinine devices, in the hopes that someone will accidentally buy them.
10USB Mouse Jiggler
The USB Mouse Jiggler is a USB device that you plug into your computer. The device 'jiggles' your mouse around every few minutes so the sleep mode or screen saver doesn't come on, presumably so you can snooze in front of your computer and still look like you're working.
Why It's Pointless
Inventing gadgets for the lazy man is what makes America great (hell, we use Segways on our treadmills) but paying $30 for something that replaces 10 seconds worth of mouse clicking (the amount of time it would take you to adjust the sleep mode timer) is on a whole different level of laziness. This is on the level of hiring a guy to operate your TV remote for you.
9USB Eye Massager
The eye massager is a peripheral shaped like two fingers ready to attempt a Three Stooges-style eye poking. So it makes perfect sense that they'd sell it as a USB device meant to be used around your eyes. It has two distinct vibrating settings: high speed, (which we're assuming is fatal since it would vibrate right into your brain) and low speed (which, while not fatal, probably causes major retinal damage and subsequent blindness).
On the upside, according to the creators, this is pretty much mankind's greatest invention ever. Not only does it soothe your aching eyeballs, it also relieves tension in the central nervous system, aids digestion, stimulates the lymphatic system and fights against infection by boosting your immune system. The creators are already working on a USB back massager that cures cancer.
Why It's Pointless
Before you enthusiastically plunge this device into you eye socket, consider this: why on Earth should you risk blindness when you could just use your own fingers to massage your eyeballs? We aren't entirely convinced by the creators' claims about the devices' supposed magical healing capabilities either. We're not saying they're lying (legally we can't), we're just saying they have something in common with Pinocchio (i.e. both are fucking liars). If you're still considering buying this, then we urge you to take the price into account. We can assure you that there is a multitude of less expensive ways to blind yourself such as peppering the eyeball or a good old-fashioned eye stabbing.
