How Well Does The Samsung C-Pen Stylus Work With The S4

[itsallgood]

So, I bought a $5 universal stylus from Walgreens to use with my S4 to use with S-Memo to draw measurements. It worked really well, even though it has a fat point. After doing some research online, I see Samsung made a C-Pen Stylus for the S3, that should work with the S4. These are some of the things I would like to know:

1) Will air view work by just hovering the C-Pen over the screen?

2) Does the menu and back button work using the C-Pen?

3) How well is wrighting and drawing with it?

4) How do you like it?

Thanks
