Love the pen as I use it in clinical a lot. But the ink doesn't last long- One ink vial lasts only for one care plan I find. I love it because I can erase. I'll probably only use this pen for documenting. yes, Stock up on ink.

I LOVE, LOVE, LOVE this pen!!! I don't, however, love how quickly the ink runs out. Be sure to stock up on PLENTY O' REFILLS. I do all of my Calculus homework with this puppy. I can color-code everything and I don't have to worry about pencil smudges or fading, nor do I get eraser shavings all over my bed, books, and desk.

I purchased this pen for my friend after purchasing the orange pen for myself. I use the pen in my planner on a daily basis. The ink dries quickly so I have yet to experience any smudging. The refills are easy to replace, the pen writes smoothly with no skipping and the eraser is easily my favorite feature on the pen. After showing the pen to my step mother, she said she couldn't wait to order one. If I make a mistake or need to change something in my planner, the eraser cleanly erases the ink with no residue, nothing to wipe off the page and the ink is gone with only the impression of the original writing left behind. I have yet to feel so impressed by a pen. If I had the money, I would buy one in every color!

Love this pen! I bought the metal gradation blue multi-pen, and it is BEAUTIFUL. Love the full metal body feel. The weight and the balance is great. Only disappointment is that I ran out of ink on day one. :P

Great for working on ochem! I can color code everything without having to switch pens. And I don't need white-out either! :)

Just an fyi, the "black" ink is more dark gray. Also, I've read a few other reviews that say that the ink is "scratchy" but that hasn't been the case for me. It comes out nice and smooth, but this may be because I press lightly and write more at a 45 degree angle than a 90..

A great multipen for everyday use. I carry this baby with me everywhere attached to my hobonichi. The only downside is that it's an ink guzzler. I don't know if I've ever had to refill a pen before, but with this one I've refilled it twice already. The black and blue ink. It's a great feeling. I've bought another, but the dark blue one as a graduation present for someone. I don't know which one's more beautiful.
