Just love the category buyers. Guess they never shop at Walmart. If you buy the cheapest stuff from China, don't expect a good experience. On the other hand, the more expensive China made item will still be only 1/4 to 1/2 the price of our local products. The better made China optics I like use Japan or German lenses. Companies like Leupold openly admits they build offshore.
The higher priced China made optics look way better than the low end name brand.
Most name brand items have distributor and retailer markup that are up to half the sale price. Look at Cabella's house brands which are often made in China. Often you will find the exact same item on aliexpress for 1/4 to 1/2 the price.
Yes, the really low priced China made stuff is mostly junk. From my experience, most of the higher priced China made optics are excellent value. You cannot buy the least expensive item and judge an entire country on that experience.
