I have the oldest one and I had a problem with hair growth due to polycystic ovaries, meaning that in the afternoon I would shave and in the evening I would feel like a cactus. I have had it since I was 16 years old, I am 25 now, and I have done it 15 times in each area and my secret in the application is persistence because the instructions say not to hit the same spot but I did it because I didn't see any results and that's how I saved myself. I have had it for 9 years and it still works, even though it said it has 20% efficiency on the armpits, but I insisted on the same spot two or three times even though I shouldn't have, and soon I won't have any hair even on the armpits, which I considered impossible and had given up on. I just violated the instructions

I have had it for quite some time. You only feel a slight pinch and very small burns mainly on the face! I have seen different results on the body, almost none on the face, but it may be because the hair in that area is hormone-dependent, so there is no difference. It is generally a good purchase.

Within a year of use, with a long break of about 4 months for the summer, my hair has significantly reduced. Exactly as promised, I believe about 70% will disappear if I continue. It's worth its money. Really.
