I like ProStrong, but since they don't have that many colors, I'm trying OPI for the first time? I haven't received it yet. I have natural nails and just want a nail lacquer.
I didn't find OPI to be that great. I really like Sinful Colors and you can find it at Target, Walgreens, etc. It seems to last the longest on me. I've also had good luck with Maybelline Color Show polish.
I am also a fan of Sinful Colors. I like Finger Paints too. Love the names OPI gives its polish colors, but for the price I am not impressed with its staying power.
I have over 200 polishes. My favorites are sally Hansen (diamond, compete formula, gel effects, extra wear), also OPI, Nails inc, and julep. I find the best thing is a good base coat....perfect formula gel is what I use.
