Sorry if I was unclear. I was just saying that as a buyer, you need to ask these questions, and sometimes things arent as they seem.
It looks like a nice package, but he didnt show a picture of the backpack, just the OEM case. It comes with filters, you might ask what kind of filters.
With all that being said, as long as it wasnt crashed, which would void the warranty, it's probably worth $1300, then you have a drone that still has at least 2 months worth of warranty on the major components, and you can buy Refresh for it.
Bear in mind that the new P4P V2 is out, and the seller should be aware that prices have already dropped on this model since the new version has an updated propulsion system with low noise props.
Im sorry to ramble on, but I try to avoid "special editions" of things, because finding replacement parts for them can be a nightmare. They only sold a fraction of Obsidians that they did of P4P's and +'s, and now that the Obsidian has been discontinued, finding repair parts for an extinct bird might be a challenge.
I've seen several P4Ps in the $800-900 range with 1-2 extra batteries, and I'd actually rather not have the Obsidian for the above reason: the parts are close to non-existent for it. If you crash it, you're going to end up spending more money on shell parts to convert it back to a regular P4P.
