The Keyboard and Stylus are a must have for the Chuwi Hi13. Firstly, the Keyboard adds additional IO and the typing experience is great, I would say 2nd only to the Xiaomi Mi Air 12. Secondly, the build quality is premium and I think worth the investment. Finally, the HiPen H3 Dual Chip Stylus is a breeze to use, very responsive and accurate. Although it does have a slight delayed response on Photoshop. I do recommend you use other apps such as Sketchpad, Paint, and OneNote as this is where the Stylus works best. Apparently, there is an issue with Photoshop for it to work flawlessly. So, this is not for those who intends to work on Photoshop most of the time, or a Professional Graphic Artist. Other than that, built in Windows Apps works just fine.
