Summary: The Uni-ball Signo DX (UM-151) is another great writer in the Signo series
Where I buy it: jetpens.com
I am impressed with every pen I've used in Uni-ball's Sigo series. Apparently I have the older DX model, rather than the newer UM-151, but I believe I've used the UM-151 as well.
I prefer the 0.38 size, as it fits my writing style well. The main difference between this pen and the Signo RT is that the DX is a stick pen, and the RT is retractable. This winner is available in several colors and in 0.28, 0.38, and 0.50 widths.

- The pens that I review on this blog are pens that I have tested extensively. I have occasionally been impressed with a pen, only to discover that after a few days it has lost some of its functionality. By delaying my review of a pen until I have written with it repeatedly, I hope to give you more than just my initial impressions. These reviews are obviously my opinions, and what works best for me may not work best for you. Finally, to keep these reviews as unbiased as possible, my policy is to accept no free pens from any manufacturer, retailer or blogger.
