I have tested various pins (Just Mobile, Amazon Basic, Wacom Bamboo, Cosmonaut). I turn the pins on Electronic note leadership on the iPad. Just Mobile is relatively thick (only Cosmonaut is thicker) and acting outwardly very classy. The peak is very well made. Is very good in the hand: though I have relatively small hands, I could write safely and accurately using the stylus. But the main advantage is the tip: the hardness is really good, by response time when writing appropriate, precise letters. At the same time - even when typing quickly - comes the hard outline of the tip with the pad never in contact. A clear recommendation after several months usage! However, after I tried to Cosmonaut, I Just Mobile exchanged for this pin.
