I bought 4 pens to try and this was my second favourite. It writes smoothly and is comfortable to hold.

Great pen, smooth writing experience, consistent flow. Great variety of colours. It is my daily pen, but I have experienced the ball tip fracturing.

The Uni-ball Signo RT1 has been one of the most enjoyable daily writing pens I've ever used. the Signo RT1 is smooth and runs fluidly on the page but does not smudge or create large spots of ink on the page.
