I ordered this stylus on August 19, 2011 well aware that I would probably forget I had even ordered it by the time the estimated shipping date of September 1-6 rolled around. To my surprise, it arrived in the mail less than a week later along with another BoxWave stylus I had ordered. Maybe I'm just lucky because I bought two different models at the same time, though.
Now, about this stylus. The Slimline is, in fact, quite slim; slim enough that if you have larger hands or thick fingers it may be uncomfortable for you to write with it. It is slightly slimmer than a No. 2 pencil, mostly due to the lack of edges. This model is also extremely lightweight, but not quite what I would call balanced; most of what weight it seems, in my estimation, to be focused slightly above the tip. Width wise, The body is roughly 1/4 inch wide, with the tip being slightly smaller. It also comes with a detachable clip with a tight woven yarn body (roughly 1.5 inches long) and a plastic head, which fits securely in the headphone jack of my iPad2. This is removable and re-attachable, by way of a small, thin metal key ring attached to the top of the stylus.
Performance wise, this is fine stylus. The slimness of this model allows for much more precise writing than several others I've used, and it is a relief to have the ability to actually see what I'm writing as I go. The material used for the tip is the same that is used for other BoxWave styluses from what I can tell, so there should be no worries or fears as to how smoothly it will glide across the surface of whatever you're using it on or how precise it is despite being half the width of the standard model. The only real negative that I can see in this stylus is one that can be remedied easily; the clip that secures the stylus to the headphone jack can be a bit noisy if you write with it quickly, but that can easily be solved by removing it and reattaching it later.
