This is going to depend on your intendended use. But the first thing is
probably to check if they have adequately sized prisms, chances are if
the manufacturer skimped on these the rest of the build quality will be
poor.

You can check prism size by holding the binoculars up in front of your
eyes at nearly arms length and look through the objective lens at a a
faily bright uniform source (like the sky or a a white wall, NOT THE
SUN). If you see what appears a bright square in a darker circle in each
objective the prisms are too small, the circle should be uniform if the
prisms are adequately sized.

Correction: should have said "eypieces" rather than "objective lens" in
the previous passage.
