A priori very well to do in a few months for the long-term effectiveness

It's a bit complicated to make an exhaustive review of a device such as this one knowing that the results will only really visible (I hope anyway ...) in a few months.
I will limit myself, for the moment, my first impressions and I will return later.
First of all, for me, hair removal has always been synonymous with hair remover and / or wax institute. I had never practiced hair removal pulsed light, so I have no way of comparison, whether with another device or a dermatologist.

The packaging is faultless, the device is packaged, not moving and not very heavy.
The reading of the document is what seemed the most important, as safety reminders are essential when dealing with a machine previously reserved for professionals.
We must therefore take your time, read, read well, some passages: no sunlight soon after, do not iron several times on the same area of ​​skin (I found it difficult but I back), do not look face when light appears (again I found was difficult but I will too), it does not fonctionnerai on a dark or black skin, or on a tattoo, body parts are avoided etc ...

Specifically, the pulsed light attacks the hair follicle and destroys it, not in a single pass but during repeated passages (not at the same meeting, but several times in a few months). Regrowth is then slowed or broken (that is to support or not this assumption that it will take several months).
During a session, if anything, it is quite clear that we should not board several times on the same "plot" of skin and therefore it requires concentration. Moreover, I find very great pity that a pair of goggles for the eyes is not provided in the box. Given the price, you could still be entitled to have, without necessarily having to order. It seems to me essential and I also ordered a pair on amazon.

The feeling is not bad, really, I just felt a warm light and a slight tingling sensation then.
Again, it is essential to refer to the manual to check the required intensity, according to his complexion.
The machine hums a little use, but the sound level, it's really quite reasonable (although quieter than electric epilator).
The green lights, orange or red is a real plus, and allow it to be self-confident (hence the interest of glasses, able to face what we did without being dazzled). Some passages in orange left me perplexed, though I had the impression of being properly positioned.
This new model comes with a lamp that can apparently be up to 100,000 light pulses. It's ... much appreciated!

It is important to keep in mind that we are really in a long-term program with this unit, working "in a vacuum", for several weeks or months for visible results for weeks or even months later.
As for me, I am rather optimistic about the quality of this product and on future results.
