I bought this item to go nature viewing and must say that it really is a great binocular for the price.  The items viewed have a really nice 3-dimensional look to them and the diopter comes in handy even for someone with very bad vision like myself.  The focus for this model (16 x 50 Wide Angle) is a flat tab between the barrels that makes it VERY convenient to use without having to look or stretch your fingers.  It gives a very nice field of vision and has roll down eye cups, which is good just in case you want to wear your glasses or shades.  The binoculars do shake a little b/c of the power of the magnification.  And it can be a chore to hold for long periods of time b/c of its weight.  It weighs about as much as one of Michener's hardback novels.
