Amazing pen, great flow...

Amazing pen, great flow and consistency. Didn't skip. It's not the nicest looking pen but overall it's still nice to write with.

Great pen, for what it is. The lines go down smooth, consistent, and dark without the blobs common to a lot of gel pens. Pilot "Choose," I'm talking about you here! Generous amount of ink in the refills, which allows for plenty of writing. I would rate these even higher than the Pilot Hi-Tec C, and certainly more affordable.

I am obsessed with this pen!
This is definitely the best pen I have ever used, with great smooth and crisp writing. The grip is just right, and I love this pen. For the price listed, this is possibly the best catch on the site!

Thanks jetpens!

This thing feels like heaving when writing on paper. it's soooo soft and precise. I use this pen and the jetstream I have and prefer this over the Jetstream. If you are trying to find out which pen fits you best, definitely give this one a shot!
