As a serious buyer, I will write this review carefully. The patient buyer can be a reference. 1: Pre purchase: customer service attitude is good, warm and tireless. Thank you very much, Xiao you. You have revised the area several times before shooting. You still have a good attitude. The budget list is also detailed and professional. 2: After buying. First of all, I'd like to praise the logistics. It's very good. It's five or six days to arrive. The packaging is solid and the damage is very little. It's not negligible. Secondly, the ceramic tile itself, I think the quality is good, the flatness is good, I am very satisfied, the overall effect map will be added. Thank you again for your help in the process. 3: After sales, I think this is also the most important part for many buyers. I try to be objective. First: as far as my personal feeling is concerned, there is a gap between the enthusiasm and enthusiasm of customer service before and after buying (excluding Xiaoyou, thank you again), such as replenishment, return, tile color difference and other issues. Here is a chat chart. Second, replenishment. I believe that every buyer is quite anxious when replenishing. When asking, your anxieties will be in sharp contrast to customer service's leisurely (with pictures). Personal replenishment logistics is that the third day after taking the replenishment, there is delivery information. Third, color difference. There are two big floor tiles with color difference with others, which is not very big, but it can be seen that the customer service replied that "it doesn't look very obvious". Later, I'll try to see if I can take a picture with obvious contrast (it's difficult, because it's inconvenient to return, tiles cut it into water pipes). Fourth, return. Customer service can return two packages at most, and 15% will be charged for others. There are pictures. Tile slate arrived, the thickness is just good, no color difference is my favorite color, the overall effect is good.
