    This is a decent pen. I like the look and feel of the Sarasas better, and I ended up preferring their 0.5mm tip to this one's 0.38 point... it's just too fine for me. Better suited for drawing than writing in my opinion.

    I've used this pen every day for over two years. I keep them in my office, in my handbag and at home. I write best with a slim bodied pen and love the blue-black ink.

    I don't think there is a material difference between the ink output of the RT/DX lines. Other than the obvious ink capacity of each refill, I prefer the retractability, grip and design in general of the RT. Definitely one of my favourite gel pens - it writes a lot better on 'normal' paper than the Hi-Tec-C line, although I still prefer Hi-Tec-C 0.3mm tips if I have better quality notebooks to use.

    I was looking for a pen that has water-proof ink & retractable. This Signo RT 0.38 the best gel pen ever : )

    Blue black color is very easy on eyes, and it looks beautiful on cream colored paper. I've been using this for last half year, and now I cannot live without it!! Grip is hard & comfortable (I don't like too soft & squishy grips...), retractable function is really functional. Comparing to Signo(DX UM151) 0.38, Signo RT is much better because it does not smear at all. Some colors in Signo(DX UM151) 0.38 smears so badly...probably due to their differences in ink flow?

    I also recommend Uni-ball Signo RT in Blue, for its bright blue color.
    Jetpens, will you sell the refill ink by dozen set?

    I spilled tea on a notecard the other day and found out that this pen's ink is waterproof. Great stuff!! Love the color and fine point for writing side notes on documents.

    These have become my new everyday fave. I bought a few colors and now I am back for the pack. I will be getting extras of the ones I ordered too, the blue black and the lavender black. NICE!!!

    Smoothness: okay
    Precision: okay
    Weight: light
    grip feeling: okay
    cushion: solid

    Overall: Okay. I personally prefer Pilot G-Knock Retractable Gel Ink Pen - 0.38 mm
    for better grip and better nonslip feature of the cushion.
