Product review (5 stars): Holds zero, well built, no issues, fair price.
I didn't know what to expect from a red-dot in this price range but it's performed excellently on a Mossberg 500 though many rounds, including high velocity slugs, and never lost it's zero or failed in any way. I would say this is not a cut rate budget piece of equipment and the best out there, but a very solid performer at a reasonable price.
