Query: Obviously seconds product.

The ret eyepiece arrived with a chipped 1st lens and an illuminator that would not operate unless you twisted it back and forth a few times and would not stay illuminated for more than 20 seconds. I shipped it back and requested a good working order replacement; only to be told that they could not replace it due to some agreement with Amazon, and that they would refund my money and I would have to order another. So basically I was shipped a seconds product and now have no eyepiece and am out the return shipping costs. Not a good experience.
