After three sessions I do not always see no effect, it is noted in the book that after three sessions (one every two weeks) the hairs begin to fall and regrowth is reduced gives a smoother hair, it may be a bit early to say that the device is ineffective but I still have my doubts.
Laser hair removal offers 5 power levels, the booklet says only that we should not feel burning when the flash device, this indication is rather vague, I do not know if putting a particular level device will be effective. Also noted that the device is not compatible with all skin types (see product details) and all areas of the body (face and scrutum).
The flash zone is approximately 10cm in 2cm, it's pretty good compared to what I could see on the other epilators. It will still be patient if we are to make quite wide areas of the body such as the legs and torso, especially the flash only works when the green strip located at the rear of the epilator lights indicating that the flash is ready, if you do not cover the whole of the band flashing the green band area will not light up and it will be impossible to flash which quickly becomes annoying when you are not patient.
In the end, a good quality product but that leaves me in doubt as to its effectiveness, a booklet that detail too little the principle of use and life of the battery a bit feeble I find disadvantages to this price does not take place to be.
Note: I will be revising my judgment later if I see a result after more sessions.
