When I bought this unit I was hoping for allot, seeing I was spending allot for me. Well it did not, and still does not let me down. The clarity is crisp & clear, on a starry no moon night I can easily pick out moving objects at 1000+ yards (verified by range finder). Unit mounts great to my firearms allowing me to hunt racoons at night, and I guess it would be good for the "SHTF". Also of course it works great as a monocular, the tube has tow tiny black spots on the outside, creating zero visibility issues. Run time even on AA's is great, also an nice inexpensive option. In my opinion, you cannot go wrong with one of these. As for the unfortunate guy who got a factory defective switch on one of the 3P units, I understand your frustration, but that's all it was, and I'm sure they took care of you pronto!
