I have a box of Elagos (wood, metal in small,medium, large & retractable), Wacom, Samsung, BoxWave (a mistake) & a PenGo.I mention these only to demonstrate that I've sampled a fair few. I use them all on my Transformer Prime, Galaxy Note & Galaxy S2.My single aim, until the Cosmonaut,was to get the tip of the pen to be as small as possible to enable as much detail as possible. No doubt you'll have noticed that the tip of the Cosmonaut is not small, so what happened? Well, point one;it's just so comfortable to use! Incredibly so. No metal clips to dig into your hand or (worse still) scratch the screen. Ever so slightly soft to the touch it feels like it's going to last a long time in a way the others just don't. Not even the ones that comes with spare tips/nibs. When I'm getting carried away on the pop-up key board the pen does a magnificent job of equalizing my random manic stabs effectively without damage to pen or screen. Drawing is a work in progress. I thought that it wouldn't be very good, but it is. So my final evaluation is not baked just yet. This is going to come out very well. It's a fine pen & I'll recommend it for sure. Watch this space for the final analysis. Thank you for watching.
