The pen is definitely worth the money. When unpacking you realize the weight that here a lot behind it to material. Even the clearly speaks for the stability. The build quality is top, apart from a few small superficial finishing marks. However, this will in the price range absolutely fine. Especially when you consider that the pin in use sooner or later, so time would collect one way or another scar. In the essential points, there are no complaints. The threads are exactly, all parts fit together perfectly and the ergonomics is great if you do not have to little hands. The Mine Factory established writes easily and evenly. Anyone who wants can use all standard jumbo refills or PR4 with adapters from Fisher (Space Pen) here.
Upon opening of the pin is the thread on pencil body the crux. Here a left-hand thread is incorporated, which prevents accidental disassembly of the pen when opening the cap. Works fine if you know that, or just the other way around tried if it does not work in the "normal" direction.
Conclusion: A great pen that does not need to hide and still significantly more expensive models. Solid, comfortable and with a design that clearly geared to practice.
