After initial "difficulties" it now works very well. I'm super satisfied, even if I have to redo my nails after about 2 weeks, because they no longer look really nice. The only point of criticism is for the colors. With the exception of the red tones, the colors are partly very different from the picture on the website. Sunset Lover, for example, is more pink. Sunday Brunch very pink and not really nude. Nevertheless, I would recommend doonails without hesitation! The customer service is also top and very eager to clarify all concerns uncomplicated and quickly! For this both thumbs up!
