The device makes first a high quality and durable impression on me and is ready for use immediately, I like that - so no charging of handheld devices, the device is powered by AC adapter. The manual is built up good and understandable and has first pointed out that one should first test the device on a small area and wait 24 hours and then to see if you would be a complete treatment tolerated on skin. If massive redness or pain, you should refrain from the use. I've tried and fortunately tolerated.
But since I have a very sensitive Hauft, I first went the next day with caution to work. To service: the unit is not heavy and is comfortable to hold. I've only tested the great attachment for sensitive skin, because I have to get used to it once my skin wimps. One can choose in the treatment between 5 Intesistätsstufen, also here I first kept the ball low and am joined with Stage 1 and have ventured to stage 3. The treatment that I have well tolerated, but could tell by the slight redness of my skin that it is better to start slowly and carefully, especially if you have epfindliche skin. The device should not thäufiger than 1 x per week apply. I try it currently even only in 2-week rhythm.
I am satisfied with the device and when I think that I pay for a treatment in the cosmetics between 60 and 90 EUR, I find the price in order. But must agree with another reviewer that the self-treatment does not replace the relaxed atmosphere at the beautician, who still gets to work with various creams, etc.. And what I have to complain about is the lack of information, where do you get the replacement filter, in particular because it is pointed out that one should exchange them for hygienic reasons after each use. Since this is but for my taste no error on the device but on marketing, which has for me does not affect the overall, so I want to forgive the 5 star for a thoroughly enjoyable device enthusiastically.
