I was shocked at how amazing it was to write with this; it made taking notes tolerable, and almost enjoyable! Unfortunately, I can't say the same thing about the longevity of the refill. I start off the day with a new refill, and sure enough, about 3/4 of the way through my last lecture every day, black-gray-white... scribble, shake, scribble... nothing. It is so disappointing to enjoy using my awesome Sharbo X so much, only to find out that it takes around $3.00 per day to use it. If I don't find another place to buy the ink, I'll regrettably have to start using another pen of less quality.

I love the dark smooth lines created by this refill, but i found that within one or two days of using it, it started to bleed out the tip in small increments. This bleeding would cause blotches on my paper that were undesirable. I keep the pen in my pocket and I feared a larger bleed that would ruin my pants, So I discontinued the use of this refill. I recognize that it may have been that i got a defective refill, and i will attempt to use the second one that I bought at the sametime and hopefully have better results.

This is a smooth gel pen that is comfortable to write with. However, it runs out of ink in no time! (I'm writing thesis notes on a Black n' Red 8x12" notebook, and the refill runs out in 4-5 pages.)

Writes well, but runs out EXTREMELY fast. I'm a student, and I noticed that even before 4 lectures that are around 1.5 hours each, the ink had run out. I'm starting to second guess my Sharbo purchase. The look, feel, and function of the pen are great, but the constant refills just seems unsustainable. We'll just have to see over time.

Bought these as a refill for my Livescribe 3 --> they arrived exactly when they said they would and in fantastic condition. These are a perfect fit for the Livescribe and they write fantastically making them well worth the price!

I bought this refill because it fits perfectly in my Livescrbe 3 Smart Pen. And it does! It writes far better then the crap Livescribe refills. The only problem with these is how long they last. With constant lecture notes and composition, each of these only lasts me about a week and a half.

Best gel pen I have had. They usually don't work well for me and was hesitant to try this out, but definitely didn't disappoint.

I love the way this refill writes. BUT!!! it runs out way too fast. Used just one day and already had to replace with another refill and for the cost of the refill it just doesn't pay to use it. Too bad I really wanted to like it. Hopefully can find another refill that is gel and doesn't run out quite so quickly. :'(
