I have a USO 1.8x10x37 illuminated.
It is a good scope at 10x, but the FFP makes the reticle disappear for me on 1.8X.

I have a NF NXS compact 2x10x42 C458 illuminated that is SFP.
The reticle is a double image on high illumination, but at least I can see it.

I got my USO scope in 2013 for cheap.
Then I realized I had the adjustable objective off by 180 degrees in the double pitch threads.
That scope had gone from owner to owner every few months for 5 years.
I called up USO and told the woman, "I could unscrew this screw right here..." She screamed at me, "DON'T TOUCH THAT SCREW..... send the scope back and we will fix it."
I almost let the Nitrogen out, I think.
Other than yelling at me once, the USO people are very nice and fixed it for free.
