TWIN1 R4C Remote Controller

This is a TWIN1 R4C remote controller compatible with Canon cameras. Please check the photos for compatible models. The operating range is up to approximately 100m. I haven't used it for a while, but I tested it wirelessly with a spare battery on a 7D, and it worked. Of course, I haven't tested it at 100m. I've only used it a few times since purchasing it, so there are some minor scuffs around the battery cover, but it's generally clean. The batteries seem to be usable, so I will include them.
