I would say that their quality is good enough. For the price they are a very good buy. I have 3 of them - 2 Buck Gold 56mm and a TRS-1 50mm. I've had issues with the reticle falling down on one of the Buck Gold's in the past, but the lifetime warranty through Bushnell, who now owns Millett, is hard to beat. I got a brand new on in the box delivered 2 or 3 weeks later.
