Well ... was expecting something else

The glass globe seems to be poorly processed, everywhere you can see stripes and spots (in the glass, so you can wipe nich or so!). Have many such balls are seen a lot nicer. Although man's hand puts it goes a little bit thicker beam to a finger, 2 or even more of these beams does not produce the thing unfortunately.
For my taste, it is also just a little too big ... I would probably have to take a closer look at the data.
