|Wacom's Bamboo series of styluses|
I received the Bamboo Solo stylus gratis from Wacom for the purpose of evaluating it for use by children, particularly special needs children. I evaluated it concurrently with the Studio Neat Cosmonaut (which you can read about in it's own post).
My initial impression is that it's very pen-like, which is what you would expect, but you would be surprised at how little like a pen many cheaper styluses feel. It's a little shorter than a standard pen, 120.8mm. The barrel's diameter measures 9mm. According to Wikipedia, the standard pencil diameter is 6mm-7mm and it's length is 190mm. It looks like a pen, it feels like a pen. That's good because our kiddos are practicing to be able to write, draw and color with real pens and pencils.
In a Nutshell: Great design, very much like a traditional writing tool. A good pick when working on more fine pen and pencil skills. I'd choose this one for handwriting practice in particular. An excellent choice as long as your child is not a chewer like mine is. :)
