Eye relief= ok (no better than others with 18mm eye relief.)
Image quality= Was compared to a Barska Blackhawk $100.00 spotting scope 20x60x60.. At 60x focusing on an brick building just under 1 mile away, the Barska had more definition.
Image brightness= Better than the Barska but kinda washed out.
I may have got a defective one because it seemed hard to focus in the middle of the image and clear around the edges??? Discounted cost to return with $750.00 ins. $12.00 This was by using my Employers UPS account and they do high volume so it is about 1/2 price.
Pros: None
Cons: Not as expected
