      Accurate,Easy to Use,Strong Construction,Compact,Quality Lenses



      Very good eyepiece! Strong and sturdy construction, very high quality. It's extreme field of view is a joy to use. The minor downside for some people might be the construction of the eyeguard, the twist option, as its hard surface is not soft to the eye.
