CONID currently does not sell the Kingsize Bulkfiller with the CAISO system - apparently they are ironing out some manufacturing issues. Based on email communication, it seems they will not be back until April at the earliest (six months from now). They do sell a non-CAISO Kingsize Bulkfiller, though, and it's €300 cheaper than the CAISO version used to sell for. My question is thus, mostly addressed to people who've tried a CAISO pen: is it worth the money and the extra wait, or should I just order the non-CAISO version? The cost is the lesser concern, since this is an expensive pen either way, so I'm mostly curious about whether you find the CAISO system useful, or just a gimmick.
