It is quite good for semi-permanent removal. Of course, first you need to file the top and then apply two coats of the product with a 3-4 minute difference between them. Quite good if you don't want to use a wheel. I recommend it.

One star and that's it. It doesn't do what it promises, you have to apply multiple layers and there are still residues left. Besides that, it caused intense itching on my nails. It smells like pure chemicals and dried out without even using it many times. Expensive for what it offers, while there are more affordable options that do a better job. Painful process with this one!! Stay away!!

Finally, it doesn't do what it says, as I have to go over the material 3-4 times and rub until it comes out. The best thing is a wheel after all.
