Ive used mine for a couple of matches now, very happy with them. The glass is exceptional. My main use for them is match shooting so not a lot of low light conditions, however after comparing these to my 10 power binos I was going to use for hunting, the low light clarity of these is outstanding. I really don't have a lot of bad things to say about them. I do wish they would make a pair of these with a reticle option.
