I am an Esthetician, and this is my least favourite polish to work with. It is all based on the brand name. The formula has gotten worse over the years like they dont care about their brand anymore. Its all about finding celebrities to make a colour so they can sell their polish. The brush is too wide and hits cuticles on most peoples nails. I prefer China Glaze over O.P.I. They have beautiful colours, but its crap to work with.
