They have a clear 1/2 inch circle close to the top center.. that doesn't belong there. They weren't secure in the box and when I opened the box, 1 fell out and broke. Is there any way I could get 2 more without the clear magnifying looking circle. The may not have been the correct ones. I was told, the circles did NOT belong there. Thankyou. Also, I can no longer use my fingerprint to get in.
