Black, Medium Tip Generic Refills for Livescribe Pulse, Echo or Sky. Smooth-writing, Premium German Ink.

I've been ordering these refills for the past few months. They work pretty well and last fairly long especially for how cheap they are. My most recent order also came with a free sample of purple ink which I thought was pretty cool.

This is way better than the livescribe brand. Eyes VERY smooth! I initially put in one refill and it just kept falling out, but I put in a different refill and it stayed in. It is perfect!

I love the turnaround time, the cartridges last the amt of time one would hope, and they're cheaper than the ones on the manufacturer's site. This is my go-to company every time I need Livescribe Pen refills.

I have been using an echo pen for about 3 years now, I am very happy with the cost and quality of this alternative refill. It works perfectly with the echo notebooks and writes smoothly. While it did not last as long as the refills that I purchased with my echo device (about 1 month of writing, using for about an hour 5x per week), for the cost and convenience of these that did not bother me. Will definitely be purchasing again, just wish there were more colors!

I have been ordering from amazon the original Livescribe ink refills since 2009. Just now checked my order history and have order 9 total so far. But unfortunately, the quality has deteriorated over time. Not sure if it's because these inks have dried sitting in the warehouse. But for the one I ordered in Nov 2013, each ink could not even give me 5 pages worth of smooth writing and the ink would come out intermittently.Then I stumbled upon these generic ones. Seeing the positive reviews and the Seller actually answered reviews / comments about the guarantee, and also the fact that they are only a little more than than original ones, I went ahead and ordered a Black ink refile and a Blue ink refill.I couldn't be happier. First I tried each ink when I got them to make sure each wrote smoothly. Now I have just finished using the first Black ink refill and it gave me a total of 52 pages of writing on an A5 Notebook.Yes, the other comments about the ink seems a bit "loose" is true but it doesn't bother me. The ink come out smoothly and at at the 52nd page of writing before the ink finally ran out, it was still writing as smoothly as the first day I used it and the ink stroke is as dark and thick as before.From now on, I'm sticking with these generic refills - who says generic is not as good as the name brands?

I had to write a review because I saw so many negative reviews. Im a student and use my livescribe pen for at least 9 hours a week, if not more. So I get good use out of it.When I was using the livescribe refills I was lucky to get a few weeks out of the refills. I've been getting about double the time out of these generic refills. That's incredible to me.Also with the livescribe refills I would always have problems and the ink would never flow normally. I would be mid lecture trying to get my pen to work! So frustrating! And if I didn't have a refill on me, then I was screwed. Well no more of that with the generic refills!!As I said I haven't once had a problem with the generics running out until the end of the refill. (See photo, ink is still pretty dark right up until it ran out)Do I wish is lasted longer? Of course! But this is WAY better then the alternative and lasts A LOT longer as I said. I plan to buy the fine tips in hopes they will last a little longer and of course write thinner. I don't use this for everyday activities, I use this for recorded lectures and note taking.A big thanks to the creator!! One less small thing to drive me nuts!!

1 of the ink cartridges was dried out when it arrived ... only enough usable ink for a few minutes. otherwise the other 4 were fine (so far).

Ink works great witht the smart pen.
