The binocular assembly was sloppy and shows a lack of care and review of the final product.
One of the lenses was not screwed in correctly and in another there was a loose prism. Both problems were easy to solve with a small screwdriver and screwing the lens in place, but this shows a lack of diligence in assembly.
