BackWhat to watch for when purchasing the product?

Don’t open the package as soon as you get the product. You should firstly check whether the external packing is new. If it looks old, then the product might be the inventory. Secondly, you should check the sealing label of the packing box. Usually there should be a one-time sealing label on the packing box. If the packaging has been opened before, the sealing label must be damaged. But some merchants would like to find some excuses by saying that they must check the products by unpacking. So if you don’t have strong judgment, you’d better ask for an unopened product. Because it’s hard to tell whether the packaged contents, such as battery or other original accessories, are original or not when there is no comparison. What’s worse, the accessories in opened package might have been replaced.
