Customer service used to be amazing but now, almost all products have the "75 day buyer protection" that does not include return shipping reimbursement. Almost everything on the app is cheaper to buy from China but it will cost you more to return it to China than it did to buy in the first place so, if the item doesn't work properly, you may get stuck with it. Customer service suggests to look for "free returns" in the product description but almost no products have it and can't filter search.
