Hmm.
I have a Bamboo Fun and the stylus from that doesn't work on my Note 3. I guess it won't work on my 10.1 either but it's upstairs and can't try it. EDIT: Just seen that the "Feel" is specifically for the Note. I thought it was just a stylus from another graphics tablet
I find the S-Pen very hard to use being so thin. I am forever pressing the button.
I press the button accidentally but when ever I WANT to press it, I can never find it :-/
I have one and I use it more than Samsung SPen. Feels like a regular full size pen. Everything works including the popup screen if you press it on the stylus.
