Sometimes, you just want to see what's in your ear. What are your options? A mirror doesn't really work thanks to your eyes being inconveniently placed on the front of your head. You could take a picture, but it's tough to get the focus right. That's why the Multi-Use Ear Mirror was invented: to make peering into your ear easy as pie.
Just take a peek and you'll be able to take a quick assessment of just how much earwax you have or just how horribly infected that DIY piercing you performed is. What could be more useful than this? No, seriously tell me. I can't think of a single more useful item.
