Worth every penny and much more!
I bought this along with the "Uni-Ball Clipturn 3 in 1" and the "Uni-ball Signo Premier Rollerball" which are both estimated to arrive before this pen and I've used this pen for about 2 hours, normally given the extensive speed and amount I write my assignments with I just use my laptop to type them up; nope- not this time. I wanted to test the comfort and ink-flow of this pen, I had used a Uni Jetstream before and this lasted me around 2 1/2 years which is pretty good given I was doing 3 sciences, english lit and language and art (Yes, I used it to draw). This pen is a straight upgrade from the essentially stock-no frills one. The nicely integrated pencil is easy to access and no, it doesn't activate accidently as one may think and the writing, oh it's a pleasure to use, I found myself looking for more information just so I could use this amazing product, and does it have a nice rubber grip? Hell yes! The different pen switches have a sleek look with a line on them indicating the colour of the pen correspondent with that switch, it looks fancy- and although plastic, it feels durable and firm. I would recommend this to anyone, keep this up Uni.

Excellent multiple for the price
Excellent pens. It's a shame I keep having to buy them because they go missing.

Smooth fine line
Good quality, nice to handle. Produces a good solid line with no skipping more akin to gel rather than oil based ballpoint. Black, blue and red are really nice, green is a bit meh. Pencil works fine.

Great pen!
Great pen - writes really nicely. However the only downfall is that the ink runs out very quickly. Much quicker compared to your average biro. Perfect if you need a pen with multiple colours.

Smooth and bright. If you're tired of dull coloured ink... GET THIS.
I just had to write a review straight away. If you've grown weary of really dull coloured ink this is the pen for you. I frequently need to use red and green in my work. I have tried bic multipen, faber castell ball pens and various other brands. The ink from those pens have always been really dull and not as smooth as advertised. I had just begun to accept that this was the standard for all coloured pens since the name brands were all the same. I was wrong. The colours on this are so bright you'd think it was a gel pen. Also, the changing actions from pen to pen (and even pencil!) are very smooth. It also saves me a lot of space in my pencil case as I now need one pen to do the work of 5. I had to order this on amazon through a Japanese company but it was just over £5 and delivery took about 10 days. Brilliant revision tool.

Arrived broken
Item arrived poorly packaged and damaged - now need to travel to post office to return. Also feels a bit scratchy when writing

This pen is absolutely incredible, the writing experience is comparable to using a hot knife through butter. It is so smooth and pleasant I will for sure order some more. The delivery took a while but it was well worth it.

If you like jetstream ink, besure to give this pen a try. I absolutely love writing with this pen. It is so smooth and fluid. Its always consistent and never skips. It comes with black, blue, red, green and a mechanical pencil. I bought the 0.7 mm for the ink pens and default 0.5 mm lead tip because I like having the fine tip. Was worried the pen is abit thicker than normal but it feels comfortable. Although its not very fashionable, it writes so well. It is my favourite pen to write with. Very enjoyable.
