We have surface pro 7 and the old and new iPad pros at work. I love using the pen. I use a program where there is a little or clicking and having the pen really helps. But compared to the apple pencils the surface pen seems super cheap. It doesn’t feel solid. The tip is different from the pen itself. And the tip is black, but within a few minutes the black tip wears off so the very tip is grey (as I look at pictures on line, maybe the tip is supposed to be grey). But as you touch the tip it kind of rattles. I don’t have a surface slim pen, it might feel better.
