This is about the lightest pair of 12X25s you can find. The optics are very good, I do not hunt so I cannot compare them to more expensive units, but I did some dusk owl hunting in a group and I did get to compare these against some 50 mm objectives and did not notice a perceptable difference in brightness.
For hiking and birding I think these are tough to beat. I know some say that 10X is good enough for birding and that more is too much, but I have not had a problem with these.
Pros: Light weight and small, sharp optics
