Forget this product. It has excessive distortion on the edges so there is only a small area in the center of the field that is in focus. You have to continuously focus each eyepiece while trying to hold the binoculars unless you are looking at something beyond 150 feet away. The depth of field is very short and the resolution, even when in focus, is poor.
Pros: easy to hold
Cons: excessive distortion,must focus each eyepiece, low resolution
