It's a rip off.
It doesn't work for men - I tried my facial hair and all it did was create a burning smell that made me want to puke.
I tried my legs, arms, underarms, face, and even chest and it doesn't work. I watched all of the videos, read the instructions and even called them and it doesn't work.
Plus - it has a 90 day guarantee - I had to fight for my refund - exactly 11 calls. Finally they refunded in portions and to this day I have never received a full refund. I just gave up.
Now if you have had laser or are on hrt with thinner hair I don't know it may work - but the risk outweighs the positive.
