I work with a Chinese engineering intern, spent last week with him. He was born and raised in China, and is going back soon, hopes to return.
I asked him about the products from China, and he said that the majority of manufacturers use the cheapest ways possible to make anything, it's all about short term profits.
For example, the metal itself is pure crap, the cheapest they can find. So, if you would actually need those bars to work, they odds are they will fail.
If you want them just for the looks, they might be OK if they fit.
I'd avoid them like the plague.
If for no other reason, it's a blatant cheap rip-off and if people keep buying them, they will keep making them.
Here is another example of why it's wrong - and you can find these for many companies -
Oh - and this applies to everyone that buys the cheap chinese crap - don't complain about lost jobs or low wages, you helped create the problem. LOL
