I was skeptical at first whether it actually works as easily as in the videos on Instagram and Facebook. I ordered the set and was positively surprised by the first impression. The packaging itself looks very high quality. Of course, I tried it out right away. I have extended my natural nails with UV gel and "painted" with the Doonails set For the first attempt it has not become bad, but I think here practice makes a lot out. On some nails have "bubbles" or something formed, which then caused bumps. But I am confident that it works better next time. But what I find really really bad is the supplied nail file. The is black, relatively coarse, and leaves a black file dust. Despite abbürsten with the enclosed brush / brush and abcleanern with zelette, appears after the first Powderschicht a black veil. I would strongly recommend to use another file to save trouble. The black veil messes up the entire nail design.
