Review on Uogic Pen for Microsoft Surface – Slim, Lightweight, & High Sensitivity: Ideal for Surface Pro/Go/Book/Studio/Laptop by Steve Cypert

Sticks strongly to my surface. Battery life is good. The pressure sensor works but the light ends when the range isn't as sensitive as my old Surface Pen. It might just be the protective film I'm using. It can also be difficult to align precisely, the screen doesn't mark exactly at the top, but the difference is tiny, maybe a pixel or two, so that's not a problem. To me, this four star stylus beats a five star product that costs $50 too much. Update: I picked it up because this pen was a total laugh, I can't justify being overly fussy about it. 10 out of 10 would buy again. I've added an image of the compatibility list to the FAQ that came with this device.
