I did not buy this device at amazon, customers comments m 'were afraid (carton has been opened, product used ....). I took advantage of an offer to the redoubt. But the board seems to have been opened ..... I do not will guarantee that the product has not been used .... (This feature should depend beurer?) But I have to keep still. I made 2 sceance 15 days apart. And here I see a slight profit on the legs. In places more hair, and grows slightly slowed. Armpits Jersey will have to wait. For now I do not see any change.

I am satisfied and recommend the purchase.
