Not bad! 15

The circle came with Prime as expected one day after ordering.
I ordered it because my old circle had time blessed.
Now for my design work I needed a new one.
Now the circle:
+ It is inexpensive
+ Can be adjusted easily, you do not have an extra turn the wheel (advantage of Schnellverstellzirkels)
+ Replacement tip and mine here

so much for the better.

The following issues I found:

- The compass point is after a few times using blunt, that's too bad, because the my old remained pointed several years
- He slipped extremely light, of course, with smaller circles is often the case, but here it is striking.
- Major drawback of Schnellverstellens! If you focus a circle draws, it is not uncommon that the circle by one's own power easily adjusted. These are often only millimeters but this makes itself felt on the sheet and disturb you when working imens.

Thus, I would say, on the whole, the circle is between suitable as school circles, especially since it is easy to use by the Schnellverstellfunktion, but who needs to work a lot with circles or a detailed work would (construction, technical drawing), I advise from buying cut off!
