SCRATCH & DENT: This PNW Dropper Seatpost was mounted in a short demonstration video. There are a few signs of being mounted from the demo, but altogether this item is still like new. It will no longer come in the original manufacturer's packaging, and will no longer come with any of the manufacturer's instructions/manuals. It has been repackaged for further shipping.

This dropper is hands down the best one I've ever used. Very smooth, quiet and consistent. If money were no object, I'd go with BikeYoke, but I am so impressed with PNW, I am not sure I'd want to.
