Got this via FedEx today, and took it into the garage to set it up. First, the "instruction book" provided lacks any detail on loading batteries. Do they go in positive down, negative down, one of each, what? I tried all three and my unit wouldn't power up at all (in a darkened garage). Second, there was a nasty finger print inside the viewing lens that covered the entire ocular area...not outside where I could clean it off...INSIDE! I can only imagine how that would have affected usage of this P.O.S. Sending it back first thing tomorrow for a full refund. I wouldn't get another one of these even if you gave it to me for free.
Pros: none
Cons: non-operable
