UPS delivered mine Friday. I haven't had a chance to really try them out, but I did look around with them a bit after sunset, and spent some time with them identifying landmarks out of the airplane window while serving as "head navigator" of my pop's airplane during a trip this weekend.
Low light performance is quite good. The eye box may be a bit small for some but I found it perfectly useable. Clarity is really nice. Overall I'm quite impressed, especially for the price!
Now some men like the fishing
While some men like the fowling
And some men like to hear the cannon ball roaring
Me, I like sleeping
