They did a bait and switch on me. They told me that the lenses that came from Nikon with the D5100 kit were "Polycarbon" and if I wanted glass they could upgrade me to the glass optics. What I got was a cheap off brand telephoto lens. When I called for an RMA they demanded a 15% restocking fee. When I complained they said that they would drop that to 10%. STAY AWAY! Far Away. I am going to write Nikon as well
