I love my Leupold Compact Spotting Scope, but it needed the lens shade sepecially when in bright light. The resolution of the scope is very good, after all it is a Leupold, but bright light was causing difficulty at the range. This is a very light lens shade, but there is no where to carry it when it is off of the scope - therefore it goes in the range box unless it is being used. It really helped when the sun is bright, and that is why I got the four inch model (although a shorter one would help solve the transport issue).
Pros: Very light in weight, does what it is supposed to do.
Cons: Does not fit in the case when on the scope.
