The device itself is pleasant to use. I find it a bit difficult changing heads. I use it mainly on the legs because I have cellulite encrusted plates. After a month of daily use, I do not see effective on cellulite. However I see a decrease in the orange peel. The manufacturer says it takes six weeks of use before seeing an improvement. I thought I could use this device to massage the neck that often make me suffer, but I can not support this device under the head, even at the minimum, it is far too vibrate the head and the massage heads are too harsh. For use in this location would have required heads with rubber tips, or a more flexible material than rigid plastic. Overall I do not regret my purchase even if the objective is not met at the moment.
