I am happy to write a review for my last shopping here.

I hope to express some information from the review to other people.

At least what I want to know:

1. Is the quality of the goods I bought very good?

2. how about the delivery speed? Is it procrastinating?

3. Is it convenient to refund? Do you know that sometimes the goods delivered are not right?

4. Is it convenient to exchange goods? Do you provide a perfect way of exchange.

5. When I have questions, can I contact the customer service staff of the website niddk.nih.gov in time? I don't want to wait long.

6. Is payment safe? I don't want to shop on a scammer's website, so you must at least keep niddk.nih.gov safe.

7. Please keep my personal information and payment information confidential. I don't want to report the loss to the credit card bank. Fortunately, I haven't encountered these things yet.

What's your opinion?
