The cuffs can be easily put on without any assistance, and the control unit can be effortlessly adjusted using the two knobs. Simply set the duration and intensity of the treatment. Done. The Venen Engel 6 offers you a uniform glide wave massage with six air cushions per cuff, and the overlapping technology prevents gaps between the air cushions. At just 60 dB, it is about as loud as a refrigerator. You can easily carry on a conversation, read, or simply relax. The included leg cuff for the Venen Engel control unit allows you to enjoy a pleasant, uninterrupted glide wave massage from your feet to your abdomen. The use of high-quality materials ensures a long lifespan for the device and the cuffs, without stretched-out cuffs, loose hose connections, or broken zippers.
