Bushnell Insta Focus 9X-27X50 Zoom Binoculars

Giving a pair of Bushnell Insta Focus zoom binoculars. They are 9X-27X50, with 216FT AT 1000YDS AT 9X and T2MAT 1000M AT 9X. Great for bird watching! My son doesn’t want them now. But I see some markings in the lens. I don’t know if they are still working or not.
