Useless. I have the ideal skin and hair type (pale skin, very dark hair) and so I was really hoping it would work on my facial hair as I have PMS and it's embarrassing. The FAQ states Nood should work with those who have PMS, and though I used the highest settings, every other day (or at least every three days), for FOUR months, it did absolutely nothing. Nood recommends giving at least two months for results, so I thought four would do the trick, but no. I don't think their return policy is reasonable - if you have to wait at LEAST two months for results, then you really only have one month to return, and at that point, you're JUST (supposedly) beginning to see results, and you don't know yet if they'll be enough to justify the cost of the product. I think there should be at least a 120 day refund policy. Also, even on lower settings, at times the product would literally shock me, far beyond the slight tingle I was feeling before. I had to try different things, like not clenching my jaw when doing the jawline, and make sure I wasn't touching metal or carpeting. Very disappointed in the lack of results but more so in Noods unwillingness to refund me for a product that doesn't work, despite me having the prime skin tone/hair color combination, and using the product correctly.
