Although it works perfectly at first and the writing sensation is truly unique for a pen with this type of ink, with fast drying, vibrant color, no skips, and incredible smoothness on paper, unfortunately, it doesn't last long. It's only a matter of time for it to break, start becoming rough, and leave skips, etc. It's really a shame because there is no pen comparable to it when it works properly.

The best pen that exists. I have been using it for a few years now. Uniball conducted special research to create ink that flows easily and does not clog in the ballpoint. The result is a smoother writing quality than any marker and zero smudging. Honestly, it writes so comfortably that it takes time to get used to for someone who is used to pressing down on the pen. The thickness is ideal and the lightweight plastic casing has excellent anti-slip characteristics. In a military workshop where we sign "movement" reports (for those who have served as clerks in a movement office...haha memories...), even with greasy hands, it did not slip once!! As for the price, it is indeed not cheap, but with the refills, the situation becomes completely acceptable.

Very nice writing, smooth and continuous. I would have been fully satisfied if it didn't break after 3 days of use, the ball started sticking and it leaves big gaps and doesn't write well. I sent an email to the company, no response, no interest, a shame

5 stars because it doesn't let me put more. Nice grip, although relatively large. It doesn't slip due to the rubbery surface. Incredible smoothness in writing. Intense and distinct color that doesn't leave marks on the back page, nor ink stains, while it dries so quickly that even I, being left-handed and dragging my hand over the written words, haven't noticed any smudges. Its price is a bit high compared to the rest of the category, but it's worth it. Personally, for the past 4 years, it has been my main pen (I have already finished 2), which I have in blue, red, and black because unfortunately it doesn't come in other colors.
