Anyway my new bins arrived , seemed great , but when i looked down the objective lense , one of them had a line going diagonally across it from top to bottom , the other lense is clean as a whistle , seems to me like a drop of hot glue made the thread when being manufactured.Now the seller is trying to tell me all bins have these lines
, even though he hasnt got the bins back as i only posted them today.
