I agree with other reviewers in that the pen lacks a certain substantiality. ie it feels like a toy and the control wheel has a chintzy feel to it. Also would it have killed them to include useful some documentation?

Being an artist myself, I can say that the feel of the brush in my hand is pretty important, whether working on digital art or otherwise. However, after getting this airbrush pen I realized that it has a very well-designed shape and weight.
It shouldn't be any heavier, it shouldn't include any more metal and it shouldn't feel other than what it is now. Yes, the Wacom Intuos3 pen that comes with the tablet is slightly heavier, but barely makes a difference. How you use it is what makes that difference.
I say if you're buying this, then it's money well spent.
I gave it 4 stars because nothing can be THAT perfect! But I loved it!

I am thrilled with my digital pen, it has made working with my art tablet extremely easy and I find that I can get my artwork done quicker using it. Before I ordered the pen, I did read a review saying that they also liked their pen, but warned that the pen itself felt 'cheap'. That I would have to agree with, for what one pays for it, the feel of it is, disappointingly, like a dime-store quality toy. However, I can and do overlook that fact since I love the outcome of my work. The pen that came with my art tablet has a nicer feel in my hand but I don't like to use it, it is harder for me to work with. If you can overlook the cheap plastic feel of the product and focus on the things you can do with it, then this is a good investment.

Note...off the bat this is made for Intuos 3 and Quintos Wacom Tablets...it wont work for an other tablets.

I opened the package and thought...hey I just paid money for a tablet pen with a wheel on it...what a jip. Yet after I got to play with it I could see how it will make my life easier doing painting and drawing. True you can use the Wacom pen to do airbrush...but controlling the digital paint flow is far easier using the wheel so I can concentrate on creating my artwork. True you can probably set up one of your Wacom Tablet Sliders to change the flow of paint (I actually don't know if this is possible...I already use my sliders for other important stuff I don't want to reassign) but if you can't map it to a slider...then the pain of changing the flow manually in Photoshop AND Painter would really slow my down. So I ended up thinking it was money well spent...yet I wish (this is what I knock them down for) that the pen felt a little less...flimsy. A real airbrush...which is normally made of metal and having just a bit of heft and solidity to it I find it a tad disconcerting to use the digital airbrush and then go back and use a real airbrush...
