I bought this item based on reviews, before any bad reviews were posted. This product is pretty much a waste of time and money. I used it regulalrly for months, and it definitely does NOT live up to its claims. It is NOT as effective as microdermabrasion performed in a doctor's office, and even that procedure has limitations. While it does exfoliate the skin, it doesn't do anything beyond that. Frankly, using a good exfoliating cream/scrub- or even a gentle washcloth- is more effective, less expensive, and less time-consuming. The claim that it helps smooth surface irregularities is beyond minimal. As for the claims that it helps bloodflow, increases cellular production, and stimulates collagen production deep within the skin- well, if it does that, I have yet to see the results after months of use. Additionally, the quality of the device is unimpressive. It seems kind of cheaply made, the suction device sometimes pops off, and the rough surface on the disks also frequently come off right away- sometimes just after placing one inside of the unit.
All in all- save your money! This product is an ineffective, over-priced for the quality, waste of money and time.
