This product is NOT as advertised. It took 2 months to arrive. It is a pedometer that can only be used with an app whose instructions are in characters, not English. There are NO instructions for return if not satisfied, hence customer satisfaction is NOT guaranteed. Customer service is spotty and unsatisfactory. There is NO ability to review the product on the company's website, hence the ratings of the product that the seller espouses CANNOT reflect verified buyer's opinions. The address of this company is in Hong Kong. The buyer feels scammed. Do NOT buy!
