Any comment/experience with cheap aluminum radiators from Ebay

[Anaurath]

Hi Guys,

I´m thinking about the possibility to replace my OEM radiator (GU TB45 Automatic from 98) for one of those you can find in Ebay.

They look really promising, but I have some doubts on them. They are 3 core, bigger and thicker than OEM and they say that are 30%-40% more effective than the standard one.
The only think is that they are made in China (like practically everything nowadays...).

For 200 dollars even less and sometimes including delivery costs, I would like to know if someone here have had any experience and would endorse them.

any comment will be more than welcome,

Thanks in advance,
