2. Construction & Quality (8/10): This seems to be constructed all right for a plastic pen (but see my nib concerns below).
3. Weight & Dimensions (10/10): This is a lightweight pen and not too short.
4. Nib & Performance (8/10): The nib is crisp, medium sized, and gives nice definition to your writing, esp. if you're doing calligraphy. However, I have had the nib suddenly flood out of the blue a few times, leaving me with a messy pool of ink on the paper. This happened while the pen was full of ink.
5. Filling System & Maintenance (5/10): This pen only comes with a single blue ink cartridge, which I haven't used. Target, where I bought the pen, didn't even offer refills or an ink converter. For this reason I'm giving it a lower score. I'm told the Pilot Con-20 converter will fit this pen. I converted it into an eyedropper, however, using this o-ring and a little silicone grease. Worked like a charm. I love that I'm able to use this pen as an eyedropper!
6. Cost & Value (10/10): I paid less than $7 for this at Target, which was even cheaper than Jetpens price.
7. Conclusion (8.5/10): Strong points for me were that I could obtain this pen locally and inexpensively, that it comes in purple, and that I could convert it into an eyedropper pen.
ETA: tried to add image but failed at first.
Forgive my chicken scratch. I have nerve damage in my hand!
