Thanks for the review. Your findings tally with mine. I don't have one but a clubmate got one last year. What is the eye relief about 20mm? One thing that always annoys me with these things is short eye relief. I'd much prefer the sort of eye relief you get on rifle scopes, 2-3". In fact I'm toying with the idea of drilling and tapping a one piece scope mount for a tripod and just using something like my Bushnell Elite 8-32x40. . It has lovely crystal clear glass.
