<b>The SIZE of the product </b><br/> It is difficult for us to define its size, a certain percentage of people said that the size is a bit small, and there are also one or two people say it is a little large.<br/> We don't want to be misleading, so If you feel that size has affected your use of the product, please contact us to return the item.<br/><br/> <b>The product I received is broken/missing parts or accessories, what should I do?</b><br/> We have replacement parts in our warehouse (US), so you just need to contact us and we will handle the after-sales service.
