Review on 🖊️ Fine Point Stylus Pen for Touch Screens - Digital Active Pencil Compatible with iPhone, iPad, Tablets and More (Light Blue) by Bill Roberts

Works on my S21 (it's a regular S21, not Plus or Ultra) BUT it writes in waves. In the video I used the stylus the first time and just my finger the second time and everything looked better with one finger. Update: It left small scratches on my screen protector and my husband's screen (it doesn't have a protective film))
