In the picture, I've had the polish on for two days, not protecting my nails with anything other than base coat (Depends 7-days, which is the best base coat I've found) and top coat (Seche Vite) and worked as usual.
I have two layers, to get full coverage three layers are needed for the yellow and pink polish, but it's the same for all brands.
For being a cheap polish, it's definitely worth the money, I have an unnecessarily large collection of nail polishes (several hundred) so I've tested many đ
