I purchased a (refurbished) Mavic off of eBay recently. Before the quad showed up I was doing some reading about the Mavic. I had read that a refurbished quad will have an r at the end of the s/n. Mine doesn't, but it did have stickers on the box that said (Open Box). Am I to assume that mine isn't actually refurbished and was just an open box new quad? This is just a curiosity thing.
