Just-Mobile's AluPen Digital has got to be the most easy-to-use and sensitive stylus we have ever tested

Compared to every single rubber-tipped stylus we've used in the past, the AluPen Digital is hands down the most responsive and highly-sensitive one we tested. Most of that is because of its very fine 1.8mm, polyacetal plastic tip that essentially performs as well as your finger does due to it being actively powered using the internal battery to replicate the same level of realism of a human finger - only in pen form. And that also means that thanks to the ultra-slim tip, the AluPen Digital is a very precise stylus to write and draw with. The tip on the AluPen Digital is even finer than Adonit's noteworthy Jot Script, albeit the difference in size is negligible in real world usage. The AluPen Digital's polyacetal tip effortlessly glides on top of glass touchscreens much better than any other rubber-tipped stylus we've used including Adonit's plastic-disc Jot Pro stylus. It's precise, and best of all it writes like you'd expect a pen to function when you put it up against the glass thanks to that fine polyacetal tip and ultra-conductive sensitivity feature of the whole stylus being powered to mimic the natural conductivity of the human finger.

While the AluPen Digital isn't as smart as some other Bluetooth 4.0-connected styli, it does work flawlessly with iPad apps such as Penultimate, which has palm-rejection already built-in so that you can actually take notes on a virtual lined/graphed paper using any passive stylus.
