You get yours off eBay? I'm leary, I got burned last time I bought off eBay. You never know what's gonna show up in the mail box. It says they have 10+ but have sold 40. I'm not sure what that's supposed to mean I'm not much of an eBay fan, I'll message the sender.
Btw "have 10+ but sold forty" simply means of their current inventory, they still have more then 10 available. They've sold forty of their total current inventory.
