This device doesn’t work at all, it’s just waste of money, it supposedly sucks the skin into the small needles are the shoots the product in, but it doesn’t do that. Therefor it just wastes all skin products.I would give this 0 starts if I could. Amazon really needs to implement some sort of quality control. I lost so much product trying to use this machine. It does not push the product into the skin. You’re better off using a insulin needle or crystal needle pins.Malísimo , esto no inyecta nada del producto a la piel se pierde todo. Arrepentida de comprarlo. Tenía otra expectativa.This product was missing a small part, so will not workCame in an open box. Dirty and clearly used.
