I am a college student and before using this lead I would easily go through normal lead in a mechanical pencil withing days. The reason why I rated this 5 out of 5 stars is because I tend to write with lots of pressure on the paper and the lead. This would always cause my lead to snap off every time. Since I started using this lead, I haven't had that problem not once, and it writes remarkably. I would recommend this product to anyone who writes with a lot of force, or just wants a more durable lead material in general.

These leads are of high quality-they are the best ones you could possibly find at 0.7 mm. Unlike other leads,these are very hard to break and for its price-they are simply perfect. I am very happy that Amazon made these available.

This is the first lead I have found that doesn't break while I am in the middle of writing something. I have been looking for lead like this for years. The lead also lasts a lot longer without it breaking off.

Wow! I seriously can't believe how well this lead works. I haven't broke a piece yet while writing with a KuruToga 0.7mm Mechanical Pencil that I bought with this lead. The lines are dark and look like they should for a lead pencil. If you are tired of lead breaking on you all the time then get this lead. It really pays for itself. :)

I chose this because it is advertised as being more resistant to snapping than regular lead. After a few days of use I have yet to have it snap on me while writing. It could be that it's "infused with diamonds", but it's more likely a ploy. Wouldn't they be mostly carbon anyway. I decided to test a piece and snapped it intentionally off the pencil tip. It did seem harder than i was used to. They do write with a nice dark line and I could be imagining things, but they may wear down faster than standard lead.
The price isn't more than your typical lead pack, so the only reason not to buy it is the vast avaliablilty to pick up some generic stuff from a retail store. If you wanna buy your pencil lead online, I'd definitely buy this stuff.

Perhaps a bit too smooth for me, this lead is generally good. I like some tactile feedback when writing (a subtle grittiness is nice) and this doesn't give me that. But I'm beginning to like this -- it doesn't break easily, and it's nice and dark. It will smear just like any other pencil lead, in my opinion, so I don't know why they say it won't (in the photo I uploaded, the "Smear Test" was just one quick, fairly light swipe with my thumb). The "diamond infused" bit is, I'm sure, purely marketing. But, hey, it worked on me.
