Hunter's comment

Here is the SMARTPEN, which is affordable but has excellent performance.

• Affordable smartpen for iPhone, iPad, Android
• No batteries required & No re-charging
• Very easy to use - Just connect it to the 3.5mm audio port
• You can do everything you can with a real pen.
• Palm rejection, shortcut button and pressure sensitivity
  
  Compatible with smart devices running on Android 4.4
  
  So easy to use!
  

Why do I recommend this pen?
Most of the smartpen needs to be recharged., but not with this smartpen. Need no recharging & No built-in battery! Also, the price is much cheaper than other smartpens, but its performance is as good as of any other smartpen. They are over $ 50 lower price than Apple pen. What more can I say?
