The vision was double! Could not correct, and the distance focus was dismal to boot! Impossible to get both lenses in sync and focused. And yes, I know about binoculars (30 years law enforcement, used "a few" times!) Very poor distance clarity. I returned (no problem thru Amazon) although my account still has not been credited. I ordered the 10X50 power which works great!UPDATE ON RETURN- Took a while (month) but I was credited fo the full amount including shipping, so we are square! Did buy the next lower power which work fine.
