Product replacement
After I had received the GAOMON M106K Graphics Tablet, the Pen didn't work and neither charged. So, I contacted the support. The support answered quickly (a lot faster than I did), I answered their questions and sent them a short video of the pen not working. They quickly sent a full replacement! They also answered additional questions, related to similar products, etc. Very friendly, helpful and fast. Thank you, Ciyea and GAOMON!
