Are the products made in china reliable?

I wanna modify my Mazda 3, so yesterday I've googled the connecting rods. I've found a website named Maxspeedingrods, they're from china. I saw they also have ebay store and many people buy their products. The price on their UK website is lower than ebay store, so I want to purchase from the website. However, one of my friend told me that all products made in China have poor quality. Actually I personally think it's not so terrible, I have a Lenovo laptop, it's good. Can anyone tell me how is the quality of Chinese products? Or if anyone have bought something from this website, please tell me how it is.

1. You can't promise that all products made in UK have high quality. So not all products from China are poor.
2. Almost 80% of products are made in China, Vietnam, Thailand or India. Even some of famous brands.
3. I've bought a turbo from this website for my BMW X5 last month, it's not bad, even better than another turbo I've bought for my another Toyota Landcruiser from a local shop.

If It is a manufacturer, but not a agent, If so, a manufacturer can keep costs low while maintaining the highest of standards.

Yeah, the cheaper product does not mean the poorer quality. I have bought lots of products, such as Ipad, phone, racing car parts, which are all made in China.

Your friend's opinion is not objective. A lot of products made in China are reliable, we can't guarantee all products made in certain country are reliable. We also can't doubt all products made in China. I think most of them are of good quality.

All iPhones are made in China. I would say it was reliable but of course it depends on the actual company/warehouse. Best bet would be to look reviews for the company to give you an idea of how long the rods will last.

It is not that bad.
Maybe you don't know that there are many Chinese ebay seller nowadays, you can't avoid them.
All you got to do is to study this website. It is smart for you to ask here.

Everyone in the world knows that. China is the biggest manufacture of cheap and low life products. Don't get in the trap just not buy the china product
