No offense I'd be weary of this. First of all at least two of them looks suspiciously like fakes, although it's hard to tell from that photo. (Blue and black one on bottom) looks like a few fakes posted on /r/ploompax every week. The surface should be one even powder coat not a brushed surface. Ebay is rampant with knockoffs so relying on them to only sell real units is not the best option.
Regardless these will not be eligible for the 10 year warranty real or not because ploom is a stickler for only warranting units sold by authorized merchants. IAmTheOutlander I'd recommend changing your ad & selling these as knockoffs or as second. Unless your 100% sure they are real, but I'd guess you have at least a few that aren't.
I think you mean wary* and from my inspection they smoke and feel like real Pax but I understand if that isn't enough for some people. And yes, there's no 10 year warranty because they are buying off a forum. You can't get the warranty from any Pax bought on ebay or CL either, hence the discount. Either way fake or not you will be getting an awesome vaping implement.
PM best offers and I'll see what I can do.
Update: I've only got 2 left of the 5.
