Is there any upgrade to this foot and leg massager compared to the CINCOM CM-018A? The leg massager now features a pressure sensor, providing a consistent experience regardless of body size. Additionally, it has been upgraded with an LCD remote controller and a more convenient zipper design. Why does it not work when I press the power button? Please make sure that both 2 air hoses are connected to the controller, otherwise it wil not work. How long should l use it? t is recommended to use it once or twice a day, not more than 30 minutes at a time, but you can use it longer if you feel too tired and want it to massage longer to work on the soreness. How can CINCOM help me? We provide complimentary repairs for any damage resulting within 2 years of purchase. Additionally, our customer support team is available 24 to assist you with any inquiries.
