Awful. Don't put enough coats on and I could do a better job at home with my own OPI polish. They also try and force services on you which is just not okay in my book.
A polish change costs $5, which is not bad, but still not worth it for the quality here.
I got a french polish since I have strong natural nails that I can grow out. First, She filed them so that the lengths of each nail were different. Second, she shaped them into a very odd-looking, clumsy squoval shape and was unhappy when I asked her to change it. On top of that, the french tip was unacceptable. If she didn't draw it right, she would go over it again, slowly covering more and more of the pink part of my nail until it was literally 50/50 pink/white. Also, she shook the bottle before starting and there were BUBBLES on my nails at the end.
I'm a stickler for nails and this was just awful.
