@BinocularSky Thanks for the info re. John and Strathspey. Wasn't aware of that. Still got a 10x50 that I purchased from him around a decade ago that are still going strong. Have bought and sold binos in the intervening years but could never part with the trusty Strathspey bins!
@Carbon Brush @Chris Thanks for the assistance and recommendation to leave a review. Returned them following @Tiny Clanger advice but only received the refund today. Hopefully Amazon won't try and punt them to someone else now. Left a comment on the returns page pointing out the defect on the objective lens. Have only had good experiences purchasing reduced items from the Warehouse in the past so this is the first time I've had to return something due to it being defective. Think they described it as being in Very Good condition.
