This is one of those things that's kinda gross, but probably useful, if it works as advertised. The Bebird Smart Visual Ear Cleaning Rod has a tiny HD camera near the tip, so you can see exactly where to clean inside your ear canal; the footage is wirelessly transmitted to your smartphone. The cleaning tip is made from soft silica gel, and the device heats the tip to 77 degrees Fahrenheit, which is apparently more comfortable.
Gross or not, there is apparently high demand for a device like this; the Bebird's crowdfunding target on IndieGogo was $10,000, but at press time they'd racked up $217,376. There are still 16 days left to pledge.
