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
