Is tianjinwikang.com trustworthy?

Not really an answer, but there are a few doubts put forward for reference:

1. Most high-end products, and all half-price;

2. Not many customers leave a message;

3. No negative news in the network search results;

4. Query the name of the head office in Hong Kong;

5. Head office phone number to the beginning of the 8 (personal telecommunication services), not 2 or 3 (fixed-line users). Not 2 or 3 (fixed line users).
