I use those for hunting, and like them. But I prefer others for sight seeing (larger and with traditional focus).
Cons first: the individual eye focus takes a little getting used to. The "everything in focus" is only partially true. They have a range they are focused in...you can focus them on 50 yds and everything beyond that is in focus. If you focus on something 25 yds away, then everything from 20-75 yds will be in focus. If you focus on a bird 15 yds away, then nothing beyone 25 yds will be in focus. For hunting, they are great, focus on the farthest thing you can see, and leave them. Then when game steps out, no fiddling with focus. You can adjust them if you want to change that.
Pros-once set, they work for most ranges without adjustment. Extremely light weight, they carry flat to your chest. Very sturdy, waterproof, shock proof, etc. For their size, excellent brightness, great optics. Good power (8) for woods work. Anything bigger, you lose field of view and brightness.
I really like mine, the operation of individual eyepieces just take a little getting used to.
Hope that made sense.
