Bought mine about four years ago for hunting and have been very pleased. They are a bit bulky and heavier than more streamlined roof prism design, but the trade off is super wide field of view, clarity and most importantly outstanding light transmission at dawn and dusk. Have had several buddies w/ MUCH more expensive glass remark that theirs can't compare to my $150 Nikons!
Pros: Great light transmision in low light. Super wid field of view.
Cons: A bit bulky for my hands- one handed focus (while holding rifle) is a bit tricky .
