There are some on the "sniper" forums. If your looking for something conclusive I don't think you will find it. I lot of the reviews were from relatively new users. Some people could not get them to pass box tests. Its hard to imagine how the seller can compete with large companies. Many scope "manufactors" basically order there scpes out of a catalog at the Shot Show from Japan Optics Limited, and they are manufactored in Japan, China, or Phillipies with components from those countries and a few others (a lot of the tubes are from Russia). I imagine the seller of these does the same thing. From the looks of it the seller gets in 50-100 or so at time and this basically a "generation", the next batch is Gen2, Gen3. I know some of the people have had bad ones in pretty much every generation, they bought a Gen 1, failed, waiting for Gen 2 to arrive, failed, waited for Gen 3. The wonder optics people are apparently GTG, they will take care of you with replacements or refunds, so if you do get a bad one I would expect you will get taken care of. I had ended up with long range/tactical scopes from Leupold 4-16, Falcon 4-14, Bushnell (3200), Super Sniper (10x), I think I have handled/looked through most other sub $500 tactical scopes (except the Sightron, Vortex, and Wonder Optics lines). I ended up selling all my scopes and going with the Mueller APT 4-14s. It has everything needed (mildot, tac knobs, enough travel, etc), Glass is pretty good and they are a lot cheaper. It was hardest to give up the Falcon, but I have the same scope on my 50bmg, on my LR-308 and my multiple 308 Bolt actions, and 22LR training rifle now.
