Review on 🖊️ Uogic Pen for Microsoft Surface: Palm Rejection, 1024 Levels Pressure, Flex & Soft HB Nib - Ideal for Surface Pro/Go/Laptop/Book/Studio - Includes 2 Spare Nibs & AAAA Battery by Andrew Grimes

This pen randomly activates the erase or undo function during each drawing, making any work (notes, drawing, etc.) completely functionally impossible. It has to happen and is extremely disruptive. If I needed a simple pen, I would use my own. Do not buy this product if you really plan to use it for anything other than scrolling and typing. You will be very disappointed. Note: I tested the included battery; it was fully functional at 1.6 volts and 0.56 amps.
