I have this pin bought last year for my mother because she in the past twice the right wrist had complicated broken and now with commercial pens when writing quite schwertut. The following criteria were decisive:
1. The pen should be really good in the hand.
2. He should write immediately (even after prolonged non-use).
3. The cartridge change should be as simple as possible.
Add to this the little light at the shank end, which lights up every time she impresses when writing too tight. That's a real comfort and available in any other writing instrument. The ballpoint pen my mother had ever can develop no more writing experience. Now they can write back! Toll!
Shaft, grip, the large cap, everything is clearly structured the Base Senso - unlike comparable rollerball pens with their much too small caps.
I myself have, so to speak, the "master model" in dark blue / light blue and'm four years more than satisfied with the product.
