Not as in the beauty salon but effective.

Hello, after long astray I've bought the device.
Generally, the device is easy to handle, slightly heavier than a hair dryer but well made. (For the price it should be.)
The only downside to the overall presentation of the whole package here: It was only a quick start guide A4 settled in German. The main instruction was in English, French and Dutch.
This was later a first small obstacle, because then but important information remains a closed first. (Eg the falling of the hair can last 1-2 weeks, which is why you should think so I just flash once every 2 weeks?)

Now for the comparison:
In a studio for hair removal, treatment for both legs no less than cost 170 euros. Since you then it needs to be at least 6 hair free for several years, it pays only for people who have to have a lot of money and are on the other hand is not as sensitive.
Because: A professional hair removal is quite unpleasant. I told the lady supervising me that repeatedly break off customers and especially men the treatment because it is really quite a twinge.
I can only confirm.
That being said, the hairs then fall while in the next 24 hours, but if you the huge device (at least Serving Size + set-top box) to look at what the have in their studios, which hums and 'start' needs, it is safe right to suspect that infects light intensity behind a lot more than ever a small device like the Philips could muster at once.

Therefore, it is relatively logical that we need more applications. The brighter (the dark pigment is yes as a transmitter of energy) and of course thicker the hair the more applications you must also get it over with.

Meanwhile, I have the thing 4 weeks, using it under the arms and legs already in the second application, and have to say that the hair will grow definitely under the arms slowly, partially fail already. The hair on the legs are rather brown to dark blond and therefore probably need longer to turn out, but also grow this already long no longer so fast.

The battery of the device reportedly will not last as long, is actually nonsense. I have (according to the prescribed first shop) fully completed applications without having to recharge again two.

Conclusion: One should not expect miracles and actually invest time. After that but I think that with the device a long-term Kompanen has the annoying hair to keep forever in bay.
One thing must not be forgotten. Hair roots sleep sometimes like a long time, or form generally also again. In the salon I would then each again take the same amount into their own hands, even if I have only 20 hair on the leg.

Therefore well conceivable alternative
