I bought the unit a few weeks ago, but I am now only been applied, as soon pending the long-awaited vacation! As for the device itself, it has, as well as my Vorrezensenten have mentioned, a very long warm-up time. In itself not bad, you wait just a bit longer. The result after waxing is so-so, there still remain many small hairs. Since you achieved with Kaltwachsstreifen strangely a better result. Also you had to repeatedly treat an area of skin, so you can even begin to remove the majority of hair. That after the skin is red, of course, is normal, but I am in and of itself a relatively sensitive skin type, as a precaution I have only tested the device on a small skin area, is happening because strangely nothing. And now sitting here today with numerous burns on the legs. Very disappointing in my opinion, especially since Sun gangs has now probably done for me for the most part, there probably helps only a large amount Fenistil. Conclusion: Absolute waste of money and money-with completely immature technology! Not recommended!
