I know I said "send them back" and I meant it.
If we consider binocular improvements as evolution, then these type of binoculars are on a branch line heading for extinction. To make binoculars affordable to the masses quality and robustness has been dropped (excuse the pun). I mean it! One of the tests done on early binoculars (Zeiss, Ross, Barr & Stroud) was to drop them onto a bed of covered sand from a couple of feet to ensure that they would hold collimation. You cannot do that with modern binoculars. Just thought I'd mention I do this for a living, I also am a subscriber to the Binocular list and am currently restoring a 20x120 Jap WWII binocular (my third).
