I don't know if it's useful or not. I bought the one broadcast by Guangdong Satellite TV and later wanted to return it. The customer service said there was no quality problem and I wouldn't return it. My attitude is very bad, and I even wrote it in the activity rules: unconditional return within 7 days without affecting the product; I don't know how they understand the word "unconditional". It's a scam! Later, I complained about 3 15. As a result, the manufacturer replied that the goods could be exchanged or not returned. Why don't you say anything about the product itself? This kind of after-sales attitude hardly makes people feel that the products and manufacturers are credible. It's just a one-time deal! (That Phoebe 24K gold beauty stick, I don't know if it's the same as everyone said, but let's add it, so as not to get into trouble with other regular manufacturers. )
