Well I've been looking into Chinese made optics because there is so much coming out that country. Some of it made to a marketers demand for wholesale pricing and some made for a purpose. One company that I have looked at a lot and have a working relationship with is SunClear. They make about three classes of optics.
Top class is built for their military and sold around the world to LE and Mil folks. But, as Walter ... says, it ain't cheap. Maybe $300 wholesale in lots of 1000. So the final street price here would be $450 and it does not use holographic imaging - it uses conventional curved glass. It is armored and recoil tested to 1000 Gs'. It has battery life measured in months, not days, but it won't run for a year like some of ours. For magnified, they offer first focal plane with mil-dot and multi-layer hard coating. But you are going to spend the same as you would for a good Burris or something, so what's the point?
By the way, Burris makes an armored mount that will take a Bushnell red dot and protect it. Don't know why Bushy didn't do that?
Grade two is good useful hunting glass and again it's tested for recoil, fogging, etc. They have prices in the $200 range for lots of 1000. They will sell on the streets here for $300 to $500 depending on magnification and other features. For that kind of money you have many options.
Bottom grade is Wally World stuff. It's true that they do not test every piece, except in tier one. QA/QC costs money. You do it by random sampling when you are at the bottom of the pile. Would I buy their scopes in Calif - maybe, but probably not unless I wanted a specific feature. Why? Because in America we have a lot of choices
Other countries are not so lucky
Would I worry if I was in the Andes and I had one of these scopes with LE/Mil-Spec build - no. If that's what was available I'd use it.
Who are these folks, Vector Optics. You can see their stuff on eBay and OpticPlanet, etc. Anything over $300 is usually pretty good and their best is right up there. If you have to face the Chinese Army some day, they will be looking at you through this gear. I would not be betting on their scopes failing.
