The manufacturer material with the product, states that this only works well (as they would re buy it) on about 80% of the users, of "correct" skintype. So even with the right skintype, hairtype, 20% of the users will not have good results, and would not rebuy the unit. That does not make the unit a scam. It means it did not work for "you". Thats the reality of products used in relation to individual variants of skin, body chemistry and body individuality. Not everyone will benefit from this type of device. We are individual and unique.
I have used the device 3 times, and have had excellent results. I have gone from shaving daily to shaving once a week. And I have very very little stubble to shave. Results are supposed to be better at treatments 4,5 and 6. Depending on area, so my results will improve.
I have used the until on my entire body, with good results. Some areas are more hairless then others, which is to be expected, as some areas with courser hair will take more treatments. This is explained in the product paperwork.
I am very happy. Do wish lamps were cheaper, but I am getting to the point of once a month use, or "as needed" which helps. I also shop around for best pricing, and have bought some extras with coupons etc.
