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!
