Query: Not worth buying

I got this free in a promotion and that's about what it is worth. It is much more convenient to use the cleansing pads by hand rather than with the skinvitalizer. I am really not sure what they purpose they think they are serving with this product. The pads are also more soapy than I would like but that is minor enough since I can just squeeze out the excess.
