Input:
These were bought for doing some animal sighting while on vacation in Central America.  They were comfortable to use, provided just the right level of magnification for middle distance spotting and took up very little space in our day bag.  These binoculars are rather sophisticated for their size and price range, providing different types of adjustment to maximize viewing.  It did take us a brief period of adjusting and experimenting in order to get the maximum result.  Putting in the time to get it right was well worth it.  They do not provide the greatest magnification or the widest field of vision, but do quite nicely for a small compact device that is easy to carry and, with a little adjusting, very easy to use by both children and adults.
