I am pleasantly surprised by the stylus. It connects easily to the bluetooth application on Paper ipad air, it gives free access to various paid tools such as brush, pencil, color mixing, and it also allows you to draw by placing the palm of the hand on the screen. This last point is particularly useful to me as I struggle to draw accurately with the hand in the air! We return the stylus to erase, or using two fingers and rotating in the opposite direction of clockwise to go back (in English, "undo"). Then we can soften the pencil tracing with a finger. On "clip" the page with two fingers to close a book, once the drawing is finished. The pen works great and Paper associated with the application, allows you to easily very nice things! Compared to the wood versions, the main difference is the material, of course, the absence of magnet to hang the pen to his ipad and the price slightly lower. This pen is expensive, but it is really nice to use. I recommend. Update: I noticed a default, the "gum" blurs (soft focus effect) instead of erasing in some cases, which can be annoying. I take off a star because of this defect.
