Blue, Medium Tip Generic Refills for Livescribe Pulse, Echo or Sky Pens. Smooth-Writing Premium German Ink.

I love the smooth writing of this refill. So far, there is no skipping like there is with the livescribe ink. This refill makes writing, smooth and effortless. Before this refill, I was constantly pressing down hard to write, or I had to go over what I had written so that I could read my notes when I wasn't on my laptop. I will be purchasing more of these, and I would recommend this brand to anyone who has an Echo or Sky SmartPen.

Much better than original ink. Been using my Echo 2GB pen for 18 months and purchased 3 sets of OEM refills. Hated getting 5 refills but only using 4 since 5th is red ink. Hated the terrible ink used in OEM refills since they are just like original ink which doesn't flow smoothly, occasionally clumps and always runs out too soon. This ink seems to write much better with less pressure. Hoping the reviews are true about longer lasting, but time will tell. The cartridge fits well and is no more loose than OEM refill cartridges. After first week of use, I would buy these again. If you are considering, stop waiting and make the purchase. You'll be glad you did.

The ink is better than the original and the parcel came much faster then what they said.

I'm posting the same review for the Black, Medium Tip because I bought one Black and one Blue refills each. I have been ordering from amazon the original Livescribe ink refills since 2009. Just now checked my order history and have ordered 9 or more 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 ones 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 refill 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 the 52nd page of writing before the ink finally ran out, it was still writing as smoothly as the first page and the ink stroke is as dark and thick as the first stroke. From now on, I'm sticking with these generic refills - who says generic is not as good as the name brands?

Flimsy with little bit no.

These are fantastic. Yes, they definitely last longer than Livescribe's notoriously scanty cartridges. They are also a dream to write with -- smooth writing, even lines. (I didn't have a problem with LS's writing quality, and yet these are noticeably better.) They are the correct size -- no need to trim the ends. Even if Livescribe acknowledged their issues and upgraded their cartridges, I would stick with these. Update: I mentioned to Livescribe customer service that I strongly preferred these to the branded version, and the CSR said she did too!

Very smooth and so far no skipping like my last batch of Livescribe ink. Fully compatible with my Livescribe Echo pen. Have not heard the 'rattle' some refer to. And if it develops I am sure I can stuff a little something in the chamber to alleviate it. I will buy again when these cartridges run out.

Doesn't fit as well as the Livescribe version so they fall out sometimes. They are obviously generics and not as good.
