BSA optics are generally the cheapest possible mfg IMHO.

Probably as bad as BSA (******* Stopped Again) motorcycles. Yeah, I had a
couple of Beezers over the years. Fun to ride but binos? I think these are
just rebadges.

But just imagine if they were actually built by Birmingham Small Arms.

The leaking oil would foul the objectives.

The vibration would rattle them into pieces in a moment.

BSA binoculars would come with a new featu "Image Destablization" No need
to focus or have a given target in mind, the binoculars randomly scan in any
direction automatically.

But they do have one good feature. Very good for dark sky viewing. Even with
the lights on high beam they will not disturb even the pickiest of
astrophotographers.
