Anyone tried this?

LCD Loupe - BiGeye LCD monitor loupe kit set - (http://www.lightcraftworkshop-shop.com/product/54)

Looks interesting. There was a Japanese supplier of loupes posted on a DIY forum that looked like a similar product selling for around a hundred bucks without the eye-cup, diopter or attaching thingy.

I would also like to know if anyone has tried this lightcraft workshop product.
