I've been using my TWSBI Eco every day for seven years and this might be one of the best waterproof inks I've put in my pen. The color is a little boring (I like bright, vibrant blues) but it is a real pleasure to write with! Most of the paper I write on is low quality (copier handouts, spiral notebooks, legal pads) and this does really well with those. As a marine scientist, the waterproof aspect is important but most other inks bleed too much.

Ever-so-slightly wetter than X-Feather Black (but not a wet ink). Overall a great performer, even on terrible office paper. Will definitely put in permanent rotation for everyday use!

This ink looks pretty, (although it seems to be a bit more purple) and holds up to its claim of being a low feathering ink. Although one thing that annoys me greatly is the dry time on it is absurd, if you plan on journaling a lot with it I would not recommend it. As I ended up smudging the ink quite a lot or straight up stopping to wait for the ink to dry. For this alone, I would not buy this ink.

Love the color and tried several papers and no feathering. Better to me than the black

This is now my everyday carry ink. It's well behaved on everything but the cheapest notebook paper (even in a 1.1mm stub), waterproof, dries relatively quickly, and looks quite professional with a sharp dark blue appearance. It's everything I was looking for and I'm buying another bottle today.
