They fit the Galaxy Tab S6 lite well. They wear out pretty quickly as you would expect from a cheap pen so for only $5 I can't complain. I mainly use my tablet for drawing and sketching and so far the pens haven't affected the quality of my work. I'm saying if you're trying to do extensive work that takes hours, you probably need to invest in a professional drawing tablet. I had no problem replacing the stylus with the included tweezers. To change the tip, I simply place the tip in the center circular groove of the tweezers, then gently close the tweezers until I get a secure grip, and then pull them out. And my tips tend to get very, very worn when I replace them and I've had no problem removing them from my trash. All in all these pens work flawlessly and I would recommend them.
