Bamboo Ink Plus
Wacom

Mine had issues with not being able to charge or use bluetooth button after a while; thanks to Wacom, I got a replacement. Pen is comfortable to use and the different nibs really let you customize the resistance of drawing on screen.

An excellent stylus in terms of responsiveness and accuracy. Very easy to write with as it's smooth on the screen upon writing with almost no lag (tested on Microsoft OneNote). The interchangeable nibs is perfect when I need to change the style of writing but so far I've been sticking to the blue nib. The price is somewhat affordable as it's slightly cheaper than the original stylus my laptop comes with (Lenovo Active Pen 2). I'm also very impressed by the tilt sensitivity which can be adjusted thus making me feel as if I'm writing with a pen on paper.
