I have looked through them. Optically, they are excellent, sharp and crisp at the center of field. I will rate them same as Zen-ray ED2. Although not nearly as good as Swarovski EL, they are worthy it for the money. I didn't get it eventually because the eyecups are too tall above the glass. I am going to share the binoculars with my wife who wears glasses. She couldn't see the full field even by pushing her glasses all the way to the binoculars. We ended up getting the ZEN ED3 that has a more useful eye relief distance.
