I randomly came across this interesting device. It's an ear dryer, for drying out the insides of your ears after swimming or scuba diving. It even warms the air it blows into your ear canal.
I was a little surprised to see this device selling for \$100 USD. Who would pay that much for this, especially when you can make homemade swimmer's ear for a couple of bucks?
I started reading the comments on the sales page and it hit me. If you suffer from chronic ear infections, then anytime you come out of the water you are potentially facing doctor visits, medications, and other miscellaneous expenses---not to mention, no more diving until it clears up. This pretty much eliminates swimming or diving as a hobby for you.
Enter the ear dryer. For \$100, you take a few minutes after each dive to clear out your ears. Presto! Your chances of ear infection are drastically reduced. If you fit into this category, then I imagine this is a great little device.
