Review on Uogic Pen for Microsoft Surface: Slim, Lightweight, 4096 Pressure Sensitivity, Tilt & Palm Rejection, Quick Charge, Flex & Soft HB Tip - Compatible with Surface Pro/Go/Book/Studio/Laptop by Donald Phi

No complaints. Nice and cooler design than Microsoft pen. Accurate, responsive and great quality feel. Needs to be charged which can be a minus except I've used it for over 10 hours and still have no charging issues. Plus a 15 minute charge (from your Surface) can give you several hours of usage. So it's hard to imagine that charging will prevent you from using it. If you're looking for a surface pen don't go straight to the MS brand, start here, I doubt you need to go further.
