Cant get one here in the US yet...plug the usb connector to your pc and have at it...look at anything where you can use the pen...the review has a couple videos and additional content...I don't know how many want to see our scalp, the inside of our nose, but this device makes it possible with using your pc usb plug in...who knows where this technology may lead someday...BD

An endoscope is a thin viewing device, suitable for being poked into places where the human eye cannot, and possibly should not, otherwise see.
Since it's likely to be dark... in there, endoscopes usually have some sort of illumination device built in. The more sophisticated kinds of endoscope shoot light out of the same lens the user looks through. The common otoscope, for peering into ears, is the simplest example of that idea.
Endoscopes are useful for all sorts of things, but they're also usually rather expensive. Endoscopes that incorporate a camera so you can hook them up to a TV or computer are, generally speaking, more expensive again.
And then, there's this one.

In the review we get a look at what his scalp looks like...BD

If you've ever felt that the world could really do with a full screen action video of you trimming your nose hair, this is the device that'll make your dream a reality. More practically, it really will let you take pictures or video of just about anything you could poke a pen into.
