I purchased these with the thought that they would have a better distance viewing and still have the quality that the Bushnell 12x50 Permafocus had.  Not so.  They did have a great viewing capability but they would not focus.  If you used one eye you could see ok but they never would adjust correctly to view through both eyes. Not sure if it was just a defective pair or what. I returned them and will get another pair of the 12x50 permafocus Bushnells.  They work great.
