Dan,
Its horrible. It looks like a back end of the 70s cheap cracker pen. Undoubtedly it will be of a higher quality but I predict it wont sell. There is too much competition from stand alone ball points that are of a much higher quality than this looks. The market does need a good click pen but this is not it! Vertex or something in the same vein would go down well.
Think your next development should be a matching pen and pencil of some style, even better to make a full scale set with RB and FP options.
Bin this one, if nothing else on cost alone, it'll never sell at more tan £20 at a push and for that you need a £3 kit and this aint it.
