llano S850 Wireless HDMI Transmitter and Receiver Set

I purchased this item on Mercari but have decided to sell it for the following reasons:
- Prime Video was not supported.
- In my environment (Teclast P50Ai), the connection was unstable unless the charging cable was plugged into the transmitter.
Considering the above, please purchase only after you understand that I cannot accept claims or returns after purchase.
The product includes everything shown in the images.
