Selling my Tangent Ripple panel. It has served me well, but I have now upgraded to a larger panel. This is in fantastic condition. 

Have used this with DaVinci Resolve and Adobe Premiere. Works like a charm. 

This will also work with FCP X (via the free Command Post software) and Capture One.

£300 new.

I think I still have the box too, so will pack it in that if I can find it.

Description from Amazon 

Getting in touch with your software has never been more affordable. Ripple is Tangent's new entry level panel with a price-tag to match. Designed for the occasional colourist, editor, and student, Ripple provides the essential three-way trackerball controls to speed up primary grading. The panel’s small footprint means that it sits comfortably beside your keyboard, mouse and tablet. Like all Tangent panels, Ripple is supported by the Tangent Mapper which means many applications will allow you to customise control layouts or build your own from scratch. Ripple is automatically supported by all applications which support the Tangent Hub which means that it should work right out of the box e.g. Resolve, Premiere Pro, Color Finale, Capture One etc. Ripple can also be combined with any panels from the Element range (including the element-Vs tablet app) so you can start with a Ripple and expand from there.
