I've read one good article on them, they were compared to the swarovski slc's 10x42 neu hd's and the author picked them as equal with the only complaint being the non locking focus on the Meopta. The best part if they are equal is they are only 999.00 compared to 2,100. And they come with a lifetime limited warrenty. I myself have never heard of them, how about you guys?
