Ah OK. That's fine then. It's just there's two fronts there I wanted people to be clear in in case they weren't aware. It's fine if you're aware and OK with it like you are.
The first being what has been said already, it's still CF equipment. So if you were expecting a quick buck, you may need to cough it back up later on.
The second being, if you did sell, you should actually wait and talk to CF about it. See what "price" they are asking for it. In this instance, hopefully it's an acceptable price (close enough to what you sold it for), otherwise, try and source another one like
@moogle is aiming for. Although I am unsure if CF keeps records of which one you were given, since they apparently can remote into the Velops to help diagnose issues or the Velop phones in if issues arise, and the only way to tell who it is, would be from it's ID. And in that case there's no way to obtain the original, so it would again be a talk with CF.
