Review on Pen for Microsoft Surface Pro 7 - Compatible with Surface Pro 6, Surface Pro 5th Gen, and Surface Go (Blue) by Tara Hammack

Excellent starter pin. If you're about to buy a more expensive Microsoft pen, give it a try as it works well and you can see if you're using it enough to justify buying a more expensive pen. One of the main differences is that flipping it over doesn't erase it (as intended), but you can always select the eraser in the app you're using to erase it as needed.
