Product Features This massage-style leg massager primarily uses a sequenced, repeated inflation and deflation of multiple airbags to create circulatory pressure on the lower limbs and tissues. This uniformly and systematically compresses the lower limbs from distal to proximal, dilating blood vessels, improving local blood supply and nutrition, and enhancing tissue vitality. 1. Simple operation and ease of use, with adjustable functions including mode, temperature, and intensity. 2. Four different operating modes, adjustable to suit individual needs. 3. Each mode has eight selectable compression intensity levels. 4. Four adjustable heat levels, allowing for warm calf warmth even in winter. Heat compress temperatures range from 45C, 50C, 55C, and 60C. A warm compress relieves leg muscle aches. 5. The product can be used individually or on both calves.
