Query: Celestron Oceana

I really wanted to give these binoculars a good review being that they are from an American company right near my home but sadly I cannot. The first pair I purchased were defective when the illuminator button fell out when I opened them to first examine them. The second pair I recieved were also defective because the Illuminator did not work at all and there was a black splotch in the viewing area that was internal and could not be cleaned by me. I give up. I will save my money and buy some Steiner's now.
