I bought the same model because the connection part of my orage c20 pro broke. This is the one that came with the set. I have the one I bought before, so I'm selling this to someone who only needs this part. It seems to be compatible with other orage models. If you want to know more, please search online. I am also selling new, unused mini heads, soft brushes, and extension hoses. If you are buying multiple items from this series, I can offer a discount on the shipping cost, so please comment before purchasing.
