its like writing with a needle.
very uncomfortable to write hearing the paper gets scratched!
also, it doesn't provide consistence ink flow.. you cant sign your name fast enough without getting no ink in the middle

I found that 2 or 3 of the lighter colors barley showed up on white paper. They also don't write that smooth, it's almost sharp feeling.

This pen.....ummm.upon using it, the tip goes in and out, like there is a spring in it,  it's not my original one!

I am in grad school and I write hundreds of pages of notes every semester. One pen writes hundreds of pages HOWEVER it started to get uncomfortable where the pen presses up against my finger. The quality of the writing out weighs the uncomfortableness after several hours of writing though...

Does not write a smoothly as I would like, otherwise a nice pen.

The day I received it was the day I knew I needed a better pen. Not thrilled about the design as it looks like it was pieced together  from three different pens. With its leather, rubber and shiny parts, it reminds me of a lab experiment from a doctor who is infamous for piecing body parts together. Unfortunately, not even electricity could bring this design alive. Still, I could have gotten over that if it didn't write so scratchy, feels like it's going to tear through the paper. It's already been retired.

After i bought this, i don't feel like writing with any other mechanical pencil, it simply feels like a real wooden pencil, even better-as one has not to sharpen it. Sharpening, i feel is a drag. I still don't understand why wooden pencils are still in use - so much of wastage of natural resources.

And thank to  Bradt Dockate above, for showing how to refill it.

This pen is more jewelry than pen, but that being said, it's also an incredible writing experience. It's not better than some of the cheaper pens that I have at less than half the cost, but it does help make you look a bit more professional in a white business shirt while at work. It also makes me feel good when I use it -- like I'm treating myself a bit. At any rate, I'm not wealthy, and I don't grudge myself for laying out so much for this pen. I think it's worth it, and several of these type of pens have lasted since the early 20th century and are still usable, so I plan on keeping this for a long while.

not very accurate, the 'needle' gets stuck and needs a tap to find it's spot sometimes.  it is possible to turn the insides a little with pliers, but you can also destroy it that way. 50/50 chance at making it better

The pen is cool but the tip is super fine.  Almost feels like your etching when your writing.  I still like it as I'm a pen geek...

The letters have smudged on there own. Smudge probably isn't the right word, but with a month of it on the tree it looks like the ink is running. The product is good but the writing is not.

The ink seems to have a mind of its own, only writing when it feels like it.  This pen is cheaply made compared to other frixion products. Still, a decent product when comparing erasable pens.

We have several of these magic write devices, this is the worst for how the drawing is displayed. Also when you tap on the face the writing also drops away very easily. I do not recommend it.

It takes a couple of uses to soften up the tip to write better, but since I have just begun to practice calligraphy I would guess that that is normal. I do feel like the ink runs out fast, but as I said, I'm new to the use of this kind of markers, so that might be normal, too.

At moments the writing can be good and at other times you lean back and wonder about it.  My biggest concern with the whole thing is it just comes across as....bland.  Like a glass of water you left out overnight.  It'll take care of your thirst but not in a way that makes you feel satisfied.

The tip if the nib came slightly bent... It required an angle for it to write properly. I am trying to return it...

I like the sleek look of a metallic surface, but it's really not practical when writing with black markers. You need to write over your lines at least two times for it to show up decently dark. With just one pass of marker, it fades into a dark gray against the lighter metallic gray background. You can still see the writing, but I find myself squinting at the board to make sure I'm really seeing what I think I'm seeing. I also don't trust myself to see the writing from any angles with the faded marker so I always have to get up so I can look at it straight on to see what I wrote on the board. It takes more effort to see what's written on the board than I would have hoped for - beyond a simple glance in its direction. The marker comes off well - too well, in fact. Even after weeks on the board, if you simply press (not rub, just press) your finger against the surface with the ink, it'll come off. There are lots of letters that have unexpectedly come off from just grabbing and moving the board about. With the standard white boards I've used in the past, the marker never came off that easily.
