> and after the first year YOU as the consumer have to prove that this fault existed when the goods were delivered.

You have to make it probable, which is very different from proving. A rule favoring consumers, something like "there isn't an excess of scratches" is sufficient in most cases, where the alternative would require an excessive cost in further analysis (read: all electronics).

> If you import the component from outside the EU the law doesn't even apply, as you have formed a contract with a trader not bound by this law.

The seller is advertising _and_ shipping his product to the EU, therefor he is bound by its laws. He even features specific advise to EU consumers.

> But in this case it's all irrelevant because the item sold is basically a spare-part

This is just nonsense. It's sold direct to consumers, it's a consumer product.
