I wouldn't dream of making grandiose claims about the image quality, mainly because I'm not constantly asking my friends to compare. I am also not a professional binocular kibitzer. But I've had no complaints. They've performed decently at dusk and dawn. The only situation in which I've wondered whether I could get a better look was when I was trying to pick out ducks and grebes silhouetted against the setting sun.
Signatures have good, solid rubber armoring.
I find them comfortable enough to hold. Their web site, and some of their product literature, annoyed me. I had to laugh at that. At that price, they're a gem. I don't anticipate buying another binocular unless I become an obsessive lister more interested in identifying birds than in understanding them.
