The set is quite good, I was initially very enthusiastic. The delivery was very quick. After a couple of informational videos on Youtube I also start immediately. The enclosed instructions explain each step very well. The nails look fabulous. Until then, I would have liked to give it 5 stars. However, I did not have a clue. After about 2 weeks I noticed a greenish stain under a nail had been easily resolved. I am in the nail forum quite by accident came across it it is verdigris which can very quickly develop nail fungus. This comes at a "lifting" since you constantly come into contact with water and this creates even under the gel and then germs. It is a super set when you work respected the first time you look properly informed and very clean. The Modulage I personally find not difficult, but since I put a lot of emphasis on a gründlche preparation, dry nails and also need loose twice Zeit.Und if a Liftig arises it will be processed immediately. For a starter kit is for me also information with potential hazards.
