I'll make no bones about it - I love this pen. Love it. And this is coming from the guy who thinks the 0.25mm Pentel Slicci is the bees knees, and lusts after the Uni-Ball Signo DX 0.28mm in brown black. Like I mentioned on the page at left, I need to do a better job of reviewing pens with a tip size larger than 0.5mm, so I grabbed this one on a whim from JetPens. As best as I can tell, this particular Uni-Ball model is most popular for the white, silver, and gold gel ink models, which are used mainly for scrapbooking. I went with a more traditional color for my first UM-153 purchase - the dark blue - and it is very nice.
From a feel perspective, the barrel diameter seems a bit wider than the Uni-Ball Signo DX, not by a great margin, but the weight is very similar. I would hope that a gel pen with an 1.0mm tip like this would write smoothly, but it is better than I could have anticipated. It just flows like the paper isn't even there, and the lines stay clean and there is no feathering or bleed to speak of. For a pen I grabbed almost out of the blue, I couldn't be happier, and I intend to try out a few additional colors in the future.
