I had a Vortex RAZOR HD Gen 2 on a rifle in the safe, and I went to remove the battery for replacement. I took a coin out of my pocket to loosen the battery compartment cap and the whole damn thing just fell out, guts and all. I don't have a clue what happened and I thought "ha, how am I going to explain this to VORTEX. Well come to find out it had a lifetime warranty "no questions asked". They emailed me an overnight shipping label and were very pleasant to deal with. I was still fairly skeptical, but packed it up and sent it in with wires and what ever hanging out of the side. They couldn't repair it, didn't ask me a question such as WTF? happened? And sent me a brand new scope today. All told it took about a week and a half or so. Kudo's to a scope company that backs their products so well. FT
