As Samsung's Note line screens are all based on the same technology, all Samsung Note line stylii should work equally well. This includes:

• Samsung Galaxy Note 4 stylus
• Samsung Galaxy Note 3 stylus
• S Pen for Samsung Galaxy Note 10.1 2014 Edition/Note Pro 12.2

Feedback

• doesn't detect very light pressure that you'd perhaps need for sketching but fine for handwriting
• The nib in Note 4 pens (probably others as well) is mounted to a spring mechanism, making the nib slightly sink into the pen when applying pressure. This makes the whole writing experience very different from the rM pen
• Just tried the Galaxy note 9 stylus on my remarkable and it doesn t seem to work.

There seem to be different nibs available, some harder some softer than the RM one. We need some more nuanced feedback:

Nibs are harder and smoother than those in the reMarkable Marker, and the shorter, narrower stylus makes for a different writing experience. Nibs are softer and writing feels less like on paper.
