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 Edgardo Ennis

The ad says it will be charged once for a few hours of use but that really disappoints me. After fully charged, it is used less than 5 hours and I cannot charge the pen. I contact customer support email address. After about 3 days of waiting for an answer, I have to return the product and get another one for my daily work. Customer service is very unprofessional.
