This is a set of G30 transmitter, receiver, power supply, and ESP holder. The receiver is relatively clean, but the transmitter shows noticeable dirt. The clip on the back of the transmitter is missing, but a holder is included, so you can use it right away. There is one issue: As shown in the last image, the battery cover opens without the cover. When using it vigorously, it's best to take measures such as securing it with tape. However, the holder holds it securely, so I personally used it as is.
