I have it and i have mixed feelings about it.
It is a disaster to bring him on. It is really very difficult. It has a somewhat strange texture, a very light, like water. It is just as if he is constantly moving.
The big advantage is that the effect is not dependent on this. I've put him many times and I think every time; f*ck this is a disaster, but subsequently found that he is perfect. (So maybe you should tell this to your client; because maybe they will panic
)
So it does not much matter how you applicator him. And compared to other uv gel polish you can lay him thicker.
In terms of impact and visibility he is very nice. I have received a lot of good comments from all customers.
I myself have had him on in the winter and I found it personally too cold. My nails were always black, which is not the intention.
Actually I find him so fun for all seasons outside for the winter.
Overall; i give him an 7; because he is a nightmare to bring on.
