Overall I would give it a rating of 4.5 out of 5

20 September 2025

It's been 2 years since I bought it, overall I'm more satisfied than not.

I listed the advantages in my first review. I'll just note that it has a more accurate color compared to the KOMZ Baigish 12x45 binoculars.

Under very bright sunlight, the colors of the trees change, the green becomes silvery, and chromatic aberrations are almost absent.

wonderful model, really honored

Cool binoculars

Tenfold increase, compactness, image quality.

Actual angular field of view is 5°, exit pupil diameter is 2.5mm. Though, this is normal for a compact binocular.
