Not as good as a professional microderm treatment

I am still trying to figure this thing out. It comes with 4 packets of crystals but the machine seems to drain right through it pretty quickly. It is enough to cover your whole face but much seems wasted and goes right back into the machine and ends up in a larger container. I need to find a way to pry that larger container open and get the unused crystals out. It hurts when you do it even on a lower setting. My face turned pretty red. It does exfoliate but I think there are other products out there that are just as good and much cheaper. Like the Neutrogena At Home system. That one doesn't have the vacuum but I honestly don't feel like you need the suction to get the exfoliation. It exfoliates. That is what it does. Do not expect anything else.More detail ...
