Review Summary

I wanted binoculars that were so small that I would never leave them behind. They are quite packable and lightweight around my neck. The image and brightness are fine for hiking and birding. I have not used them in low light or for astronomy yet. Other reviews said that Kowa put better prisms and full coatings on all of the optical surfaces. I have good quality components at a budget price and am delighted. My next purchase will probably have bigger objectives for serious birding.

Binoculars are light and easy to use - very clear to see. The 2 caps I received for the eye ends of the binoculars are the wrong size. They are useless for these binoculars. i would have given a 5-start rating were it not for this problem. (the caps for the other end fit just fine).
