Item has arrived, thanks.
Very fast delivery to Germany (19 days); well packed; all items arrived in good condition. The diameter of the glass is rather small (about 2 cm), so you get optical distortions at the edge of the lens and only a small area is magnified without distortion. The light from the two white LEDs is helpful (3 AAA batteries required, as described). Due to the small size of the lens I would not recommend it for reading longer texts. I bought it to magnify small electronic parts, and it's worth the price.
