Users and users are real customers. Isn't the customer the one who placed the order? No, absolutely not. It is the customer who really uses the product. Especially for medical equipment, the doctor is the customer and the patient is the customer, because it is ultimately used by the doctor, the patient or the doctor on the patient. Most of the demands of medical technology are carried out around end customers. Because the ultimate goal of direct customers is also end customers, direct customers will definitely recognize the products recognized by end customers. This is also the difference between industrial design and many design companies.
