Hi Elvis Ouma,
Thank you for posting in Microsoft Community.
Based on the description you posted, it seems that you have an issue with Surface Pro6 wherein you want to know if we can use any stylus pen for your Surface.
Yes, you can use a stylus pen with your Surface Pro. However, not all stylus pens are compatible with the Surface Pro. While other stylus pens may work with the Surface Pro, we cannot guarantee their compatibility or performance. We recommend using the Microsoft Surface Pen for the best experience. The Surface Pen is the official stylus pen for the Surface Pro and is compatible with a wide variety of Surface devices and models like the Surface Pro, Surface Go, and Surface Laptop, among others.
Thank you for your understanding. Please let me know how it goes.
Kind regards,
Christopher.
