Like all pulsed light hair removal devices, we must first read the instructions from A to Z. And there, for the uninitiated, surprise: it should not be too dark skin, light hair too Do not pass two times on the same area of skin during a waxing, avoid flash moles, watch the flash ... So learn about all the constraints before rushing on such an investment.
In use, however (initially after shaving), very simple and painless. Flasher area after area, and the result is a simple impression of warmth, nothing painful compared to other methods.
As for the long-term effectiveness in, I can not judge for now, after 2 uses only.
One caveat to note, for having had the opportunity to test similar devices, I find that the handling of the "flasher" is rather difficult: the "combined" is too big for my hands rather thin. Other devices are more ergonomic, allowing to more easily everywhere and can pluck one. Hence only 3 stars.
