The ink line was a tad to thin for my taste so I flexed the tines of the nib and increased the ink flow and now the pen writes like a charm. I do wish that the internal chamber held a little more ink but that is a minor criticisim.
The price of a pen can increase or decrease according to the materials of which it is made or the method of filling. Some pens use only ink cartridges, not my favorites. Others use cartridge converters which gives you the option of filling from a bottle, which is my preference. Still others are piston fill which means only bottled ink can be used. The TWSBI is a piston fill and at t$40 it is, indeed, a bargain.
The pen comes with a tool to disassemble the piston and with a small vial of silicone grease to coat the piston to prevent leakage which was, initially, a problem. The fact that the pen can be completely disassembled should be a joy to pen collectors who like to dabble in pen tweaking.
All in all the TWSBI demonstrator is a great investment and will deliver many hours of writing pleasure.
