I received my Galileo 10-30X60 binoculars, and apart from being the ugliest, dorkiest looking pair I've ever seen (grey rubberized exterior with a large "Galileo" logo onn either side), they work well. The optics seem bright, contrasty, and sharp at 10X, acceptable at 30X (not like I expected that they'd be terribly bright at 30X). The image does not stay in focus during zooming, and the diopter correction also shifts during zoom.
I'm happy with them, at 30X I've used worse cheap telescopes, and at 10X they're actually pretty nice.
