These binoculars are a small and lightweight alternative to full-size binoculars. As such they can not be expected to perform as well as their bigger cousins and in some ways they do not.The field of view is small as indicated in the product line and they gather less light in low light conditions.

I am imposed with the clarity especially in low light conditions but was disappointed by a couple features.The lense cover provided is very tight and tend to bind while removing it. It can be quite difficult to remove. If you're not careful you can pull the eye cupout of place.

I got these two days ago. The optics are very nice. Crisp and clear. For binoculars this size and weight they perform very well. However, the eyepiece cover supplied with them was far too tight, and had been crammed on at the factory, crumpling and crushing the rubber on the eye cups.

We initially tried the smaller version of these, and while they were really good, these are even better. Clear, small and light weight - fabulous for travelling. Easy to use, excellent quality.
