Purchase in December 2010. This unit is sold as modeling device against cellulite. But can do more. This unit is VERY powerful, it is percussion and adjustable rotation. design, light in color. It also has an infrared feature to massage and heat the muscle at the same time. It warms the skin, muscle mass, and disperses the celluite background, tightens and relaxes the tissues quickly. sold with 4 heads that land on body pressure. You will use rather the first shiatsu head, with its fabric and the other for a progressive in-depth work to eliminate fat. His power that you spend less time on each area. The heads are made of solid plastic for their work, some are a little noise. This compact device can be put in a bag or suitcase easily. Very long electrical cable which allows to work on the table customers. This device can work on the waist, legs, arms. - - This unit is NOT a massage arm for the back - - it does not run, it is not done. Although we could massage his lower back, massage the backs of others or get a massage the back with. The unit is fairly quiet, suitable for working in living room. I am very pleased with this purchase and I have 20 years of experience in massage. I won a trip and I was able to massage my massage and others. The engine warms a little use, but this is not unpleasant and rather ... normal. Relaxation: 10 minutes. Cellulite: 10 minutes per day for 1 month, guaranteed. The grip can be confusing but it is held by the handle or by the body in some cases. Requires knowledge of massage and drainage for the use of the heads (no detailed instructions). Excellent on sports, for couples, beauty salons. Do not allow children to play with, do not use on varicose veins or bones and in case of heart problems, among others. It's not a toy for sure. Question: How long is he going to last? Its engine seems adapted to its workload so I would say 3 to 5 years according see much use. about 50 euros seem to me a good price for this device. prices of 80 euros of certain stores are exaggerated. I repeat this device is not an arm massage and rather address is a masseur and specific areas of the body (ribs, large muscles). Summary: compact design, powerful, fast, heating, efficient, silent, recommended price 50 euros. thank you for reading.
