Very nice. It's pretty strong so it works for me. But when it comes down to it...i prefer this over the pentel ain hi-polymer led.

Super cool. If you think that the hi-polymer led dispenser is cool....this is just awesome! It's sleek and you just turn the top cap to the side to slide the led out. It fits much better in a pencil case than the ain does b/c there's no finger thing sticking out of it.

Also, the viewing window is orange tinted which is pretty cool. sorta makes the leads look orange-ish...^^

Easy to grab 1 or 2 leads
Doesn't make a chisel end as fast as other leads
!!confirmed!! It doesn't leave smudges at all when writing or erasing

Scratchy when writing
Still break way too much like any of the cheap leads do
Dispensing mechanism does loud clicks, no idea why they designed it like this

The test:
Wrote a total of 9 pages using a Platinum Zero Shin (MZ-500A) 0.5mm pencil and 12 pages with Pentel Ain Stein. On each page I made a mark each time lead broke and which lead brand I was using. In 9 pages the NanoDia did NOT break. In 12 pages the Pentel Ain Stein broke 9 times. Clearly killing both Platinum's claim of its double-chuck mechanism reducing lead breakage and Pentel Ain Stein's claim to be their strongest and least prone to breakage lead. With 0 breaks and smooth writing the NanoDia take their place as my favorite lead replacing the Staedtler Mars Micro Carbon I used to enjoy.

Love this lead. I tend to not use pencils because they don't write dark enough. This is very dark with not a lot of pressure needed, not easily broken, and not likely to smudge like it says (and this is coming from a BAD lefty writer)

I use this lead for note taking in my Pentel Smash. Stronger than expected, doesn't crumble and creates a nice dark line.

I love this lead. I have small handwriting and with the 0.5 mm lead I need something darker to write with so this is perfect.

I love this lead - I've been using it with my new Rotring 600. It's the perfect darkness without too much smearing while journaling.

I really like this lead. It holds up well, gives a nice dark line, and works well for note taking.
