Product is good quality, (this seems to be available under different brand names, I believe the product itself is the same) though the instructions were not helpful at all for me. I strongly recommend looking at some Y..T..e videos as well as a lot could go wrong. The most useful point I learnt from the video that one must not use the machine too often otherwise the collagen that has started to develop under the skin would be destroyed again and all the efforts are in vain. The other point is that a gel is essential for the machine to work, however no expensive gel is necessary, a bottle of Aloe Vera gel (e.g. 99p from a shop that sells "Bargains for the Home") will do.
