(1) Blackmagic Design Davinci Resolve Speed Editor. This came along when I bought the software license and I have never used it.
I now know that I am a 'mouse' guy and have no need for this editor. No box, no instructions, but if you know what this is you, don't need all that. You WILL need your own USB-C cable.
I have plugged it in from time to time just to keep the firmware updated, so I know it works.
I am located in the Watson area. $200 cash, in-person handover.
