Please clean up the links. Usually anything after /dp/<item_id>/ can be removed.

For example, below everything after dp/B0CXCX684S is not needed.

So instead of

You can do this.

Also you need to add the images to the PR and reference them with relative links.

@thias15 I have cleaned up the hyperlink already and added the images to PR and reference it with relative links.

I noticed several links are the same for US/EU/ASIA. Is this intentional?

Sometimes I cannot access US/UK's amazon website it will redirect me back to SG's amazon
